-Subject: [PATCH] leds: leds-gpio: reserve gpio before using it
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This reverts commit a99d76f (leds: leds-gpio: use gpio_request_one)
-and commit 2d7c22f (leds: leds-gpio: set devm_gpio_request_one()
-flags param correctly) which was a fix of the first one.
-
-The conversion to devm_gpio_request in commit e3b1d44c (leds:
-leds-gpio: use devm_gpio_request_one) is not reverted.
-
-The problem is that gpio_cansleep() and gpio_get_value_cansleep()
-calls can crash if the gpio is not first reserved. Incidentally this
-same bug existed earlier and was fixed similarly in commit d95cbe61
-(leds: Fix potential leds-gpio oops). But the OOPS is real. It happens
-when GPIOs are provided by module which is not yet loaded.
-
-So this fixes the following BUG during my ALIX boot (3.9.2-vanilla):
-
