2014-03-20random: fix comment on "account"Greg Price1-10/+21

2014-03-20random: simplify loop in random_readGreg Price1-39/+18
The loop condition never changes until just before a break, so we might as well write it as a constant. Also since a996996dd75a ("random: drop weird m_time/a_time manipulation") we don't do anything after the loop finishes, so the 'break's might as well return directly. Some other simplifications. There should be no change in behavior introduced by this commit. Signed-off-by: Greg Price <price@mit.edu> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

Remove use of regmap_irq_get_virq() in driver probe which was conflicting with use of platform_get_irq_byname(). platform_get_irq_byname() already returns the VIRQ number due to MFD core translation so using regmap_irq_get_virq() on that returned value results in an incorrect IRQ being requested.

Commit c420619 "pinctrl: pinconf: remove checks on ops->pin_config_get" removed the check on (ops != NULL) when performing pinconf_pins_show() or pinconf_groups_show(). As these entries are always enabled, even if pinconf is not supported, reading will result in an oops due to NULL ops. Instead of checking for ops, remove the corresponding debugfs entries if pinconf and/or pinmux are not implemented. Tested on OMAP3 (pinctrl-single).

Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings.
