iio: adc: at91: fix wrong channel number in triggered buffer mode

2018-11-13T19:12:44+00:00

commit aea835f2dc8a682942b859179c49ad1841a6c8b9 upstream. When channels are registered, the hardware channel number is not the actual iio channel number. This is because the driver is probed with a certain number of accessible channels. Some pins are routed and some not, depending on the description of the board in the DT. Because of that, channels 0,1,2,3 can correspond to hardware channels 2,3,4,5 for example. In the buffered triggered case, we need to do the translation accordingly. Fixed the channel number to stop reading the wrong channel. Fixes: 0e589d5fb ("ARM: AT91: IIO: Add AT91 ADC driver.")

iio: adc: at91: fix acking DRDY irq on simple conversions

2018-11-13T19:12:44+00:00

commit bc1b45326223e7e890053cf6266357adfa61942d upstream. When doing simple conversions, the driver did not acknowledge the DRDY irq. If this irq status is not acked, it will be left pending, and as soon as a trigger is enabled, the irq handler will be called, it doesn't know why this status has occurred because no channel is pending, and then it will go int a irq loop and board will hang. To avoid this situation, read the LCDR after a raw conversion is done. Fixes: 0e589d5fb ("ARM: AT91: IIO: Add AT91 ADC driver.")

iio: adc: ina2xx: avoid kthread_stop() with stale task_struct

2018-10-03T23:59:03+00:00

[ Upstream commit 7d6cd21d82bacab2d1786fe5e989e4815b75d9a3 ] When the buffer is enabled for ina2xx driver, a dedicated kthread is invoked to capture mesurement data. When the buffer is disabled, the kthread is stopped. However if the kthread gets register access errors, it immediately exits and when the malfunctional buffer is disabled, the stale task_struct pointer is accessed as there is no kthread to be stopped. A similar issue in the usbip driver is prevented by kthread_get_run and kthread_stop_put helpers by increasing usage count of the task_struct. This change applies the same solution.

treewide: devm_kzalloc() -> devm_kcalloc()

2018-06-12T23:19:22+00:00

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

It was delayed as I wanted to make sure the final driver deletions did not cause any major merge issues, and all now looks good. There are a lot of patches here, just over 1000. The diffstat summary shows the major changes here: 1007 files changed, 16828 insertions(+), 227770 deletions(-) Because of this, we might be close to shrinking the overall kernel source code size for two releases in a row. There was loads of work in this release cycle, primarily: - tons of ks7010 driver cleanups - lots of mt7621 driver fixes and cleanups - most driver cleanups - wilc1000 fixes and cleanups - lots and lots of IIO driver cleanups and new additions - debugfs cleanups for all staging drivers - lots of other staging driver cleanups and fixes, the shortlog has the full details. but the big user-visable things here are the removal of 3 chunks of code: - ncpfs and ipx were removed on schedule, no one has cared about this code since it moved to staging last year, and if it needs to come back, it can be reverted. - lustre file system is removed. I've ranted at the lustre developers about once a year for the past 5 years, with no real forward progress at all to clean things up and get the code into the "real" part of the kernel. Given that the lustre developers continue to work on an external tree and try to port those changes to the in-kernel tree every once in a while, this whole thing really really is not working out at all. So I'm deleting it so that the developers can spend the time working in their out-of-tree location and get things cleaned up properly to get merged into the tree correctly at a later date. Because of these file removals, you will have merge issues on some of these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the atomisp driver).
