Nikolaus Schaller . I have not seen the issue here myself, so please test to see if this is sufficient. I've also fixed rza1 in addition to pinctrl-single. Please also check the drivers pinctrl-mt7622.c and pinctrl-ingenic.c if mutex fixes are needed there. Regards, Tony Changes since v1: - Check if a function or group already exists as suggested by Andy Shevchenko - Make sure we always have a valid name for functions and groups as suggested by Christ van Willegen - Prettify rza1 variables as suggested by Jacopo Mondi Tony Lindgren (5): pinctrl: core: Return selector to the pinctrl driver pinctrl: pinmux: Return selector to the pinctrl driver pinctrl: single: Fix group and function selector use pinctrl: rza1: Fix selector use for groups and functions pinctrl: core: Remove broken remove_last group and pinmux functions drivers/pinctrl/core.c | 35 ++++++++++-- drivers/pinctrl/core.h | 6 --- drivers/pinctrl/pinctrl-rza1.c | 24 +++++---- drivers/pinctrl/pinctrl-single.c | 91 +++++++++++++++++++------------- drivers/pinctrl/pinmux.c | 16 ++++-- drivers/pinctrl/pinmux.h | 7 --- 6 files changed, 112 insertions(+), 67 deletions(-) -- 2.17.1
