linux-stable.git/drivers/pinctrl/bcm, branch v6.17 Linux kernel stable tree treewide: rename GPIO set callbacks back to their original names 2025-08-07T08:07:06+00:00 Bartosz Golaszewski bartosz.golaszewski@linaro.org 2025-07-17T13:21:26+00:00 d9d87d90cc0b10cd56ae353f50b11417e7d21712 The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
