2014-09-16power_supply: Don't iterate over devices to return -EPROBE_DEFERViresh Kumar1-13/+0
This piece of code was added so that we return -EPROBE_DEFER when no devices are registered. But even if class_for_each_device() returns 0, we are going to return -EPROBE_DEFER only. And so this code isn't required at all. Remove it. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Sebastian Reichel <sre@kernel.org>
2014-09-16power-supply: Avoid unnecessary 'goto' statementsViresh Kumar2-17/+5
Using 'goto' statements for freeing resources on failures is a good choice as it makes code very clean, and reduces the chances of human errors. Though in most cases compiler may take care of this. But adding unnecessary 'goto' statements wouldn't make anything better. Code becomes less readable actually.

2014-09-16power-supply: Check for failures only when we can failViresh Kumar1-10/+11
In power_supply_show_property() routine, we call ->get_property() conditionally and should check for failure in that case only. There is no point comparing 'ret' for errors when 'ret' is surely zero.

2014-09-16power-supply: Use PTR_ERR_OR_ZERO() routineViresh Kumar1-6/+2
At multiple places we are doing exactly what PTR_ERR_OR_ZERO() does. And so that routine can be reused instead of increasing lines of code here. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Sebastian Reichel <sre@kernel.org>
2014-09-16power-supply: Mark 'if' blocks in power_supply_changed_work() with 'likely'Viresh Kumar1-5/+13
The 'if' statements in power_supply_changed_work() are mostly there for taking care of races and normally they will always evaluate to true. Optimize them for fast execution with 'likely' statements. Also there is need to have better comments in code to mention about the races clearly. Get them in place.

2014-09-16power-supply: Drop useless 'if (ret.intval)' statementsViresh Kumar1-9/+5
There is no need to check the value of ret.intval before returning it, as we will be returning zero explicitly when ret.intval is zero. So essentially we will end up returning value of ret.intval as it is. Drop the unnecessary 'if' statements.

2014-09-16power-supply: Don't return -EINVAL from __power_supply_find_supply_from_node()Viresh Kumar1-7/+11
We need to stop 'class_for_each_device' loop when a supply matches with the of-node. In order to achieve this we currently return -EINVAL from __power_supply_populate_supplied_from() on successful match. class_for_each_device() is free to return similar errors in other cases as well and so the choice of return value here isn't particularly great. This commit isn't removing the Hack but making it more elegant by returning '1' instead. Also power_supply_find_supply_from_node() can return errors other than -EPROBE_DEFER now if class_for_each_device() fails.

2014-09-16power-supply: Use 'break' instead of 'continue' to end loopViresh Kumar1-2/+2
In few routines, we need to end the do-while loop when no more "power-supplies" are available. Currently we are doing 'continue' which will make the 'while(np)' conditional statement run again.

2014-09-16power-supply: Drop unnecessary typecastsViresh Kumar1-4/+4

2014-09-16power-supply: Don't over-allocate memory for "supplied-from" arrayViresh Kumar1-1/+1
In routine power_supply_check_supplies(), 'cnt' is counting the number of supplies passed in "power-supplies" field of a node. The value of 'cnt' will always be one more than the number of supplies after the do-while loop ends. And so we need to allocate memory for 'cnt - 1' char pointers. But we are allocating memory for 'cnt' instead. Fix this by not over-allocating memory. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Sebastian Reichel <sre@kernel.org>

Usually PMIC's come with coulomb counting mechanism which can be used to implement a Fuel Gauginig solution in Software itself. One of key input to these SW Fuel Gauge solutioons is the boot up parameters like boot voltage and boot current.

But, charger_manager_probe() has only checked whether desc is NULL or not. If of_cm_parse_desc() returns ERR_PTR(-ENOMEM), desc isn't NULL but desc is (void *)(-ENOMEM).

2014-09-05mm: memcontrol: revert use of root_mem_cgroup res_counterJohannes Weiner1-25/+78
Dave Hansen reports a massive scalability regression in an uncontained page fault benchmark with more than 30 concurrent threads, which he bisected down to 05b843012335 ("mm: memcontrol: use root_mem_cgroup res_counter") and pin-pointed on res_counter spinlock contention. That change relied on the per-cpu charge caches to mostly swallow the res_counter costs, but it's apparent that the caches don't scale yet. Revert memcg back to bypassing res_counters on the root level in order to restore performance for uncontained workloads.

2014-09-05Export sync_filesystem() for modular ->remount_fs() useAnton Altaparmakov1-1/+1
This patch changes sync_filesystem() to be EXPORT_SYMBOL(). The reason this is needed is that starting with 3.15 kernel, due to Theodore Ts'o's commit 02b9984d6408 ("fs: push sync_filesystem() down to the file system's remount_fs()"), all file systems that have dirty data to be written out need to call sync_filesystem() from their ->remount_fs() method when remounting read-only. As this is now a generically required function rather than an internal only function it should be EXPORT_SYMBOL() so that all file systems can call it.

The current code just returns -EINVAL because mode can't be equal to both 1 and 2. Also this function is messy so I have cleaned it up: 1) Remove initializers like "int time = -1". Initializing variables to garbage values turns off GCC's uninitialized variable warnings so it can lead to bugs. 2) Use kstrtoint() instead of sscanf(). 3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1 and 2. 4) Don't check for "mode == -1" because that can't happen. 5) Preserve the error code from toshiba_kbd_illum_status_set().
