pinctrl/amd: Remove the default de-bounce time

2016-09-07T06:32:41+00:00

commit 8cf4345575a416e6856a6856ac6eaa31ad883126 upstream.

In the function amd_gpio_irq_enable() and
amd_gpio_direction_input(), remove the code which is setting
the default de-bounce time to 2.75ms.

The driver code shall use the same settings as specified in
BIOS. Any default assignment impacts TouchPad behaviour when
the LevelTrig is set to EDGE FALLING.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

pinctrl/amd: Prepare amd_gpio_irq_handler for irq argument removal

2015-07-17T19:56:20+00:00

The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.

Search and update was done with coccinelle and the invaluable help of
Julia Lawall.

pinctrl: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-07-17T19:56:20+00:00

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.

pinctrl/amd: Use irq_set_handler_locked()

2015-07-17T19:56:18+00:00

Use irq_set_handler_locked() as it avoids a redundant lookup of the
irq descriptor.

Search and replacement was done with coccinelle.

pinctrl: make pinctrl_register() return proper error code

2015-06-10T12:49:52+00:00

Currently, pinctrl_register() just returns NULL on error, so the
callers can not know the exact reason of the failure.

Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some
-ENOMEM on error of pinctrl_register(), although the error code
might be different from the real cause of the error.

This commit reworks pinctrl_register() to return the appropriate
error code and modifies all of the pinctrl drivers to use IS_ERR()
for the error checking and PTR_ERR() for getting the error code.

pinctrl: Remove .owner field

2015-06-04T08:12:42+00:00

platform_driver does not need to set the owner field, as it will be
populated by the driver core, so just remove it.

The semantic patch that makes this change is available
in scripts/coccinelle/api/platform_no_drv_owner.cocci.
