There is error from cppcheck tool. "Shifting signed 32-bit value by 31 bits is undefined behaviour errors" Signed-off-by: edison.jiang <jiangzhipeng@yulong.com> Link: https://lore.kernel.org/r/20210316153150.1207-1-jzp0409@163.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2019-08-14Input: remove dev_err() usage after platform_get_irq()Stephen Boyd1-3/+1
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2017-04-12Input: lpc32xx_ts - check for clk_prepare_enable() errorFabio Estevam1-5/+8

2017-01-21Input: touchscreen - drop unnecessary calls to device_init_wakeupGuenter Roeck1-1/+0
Calling device_init_wakeup in the remove function is unnecessary since the device is going away, and thus won't be able to cause any wakeups under any circumstances. Besides, the driver cleanup code already handles the necessary cleanup. Similarly, disabling wakeup in the probe error path is unnecessary, as is disabling wakeup in the probe function in the first place.

2014-01-06Input: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
