Hi all, After merging the mfd tree, today's linux-next build (arm multi_v7_defconfig) failed like this: drivers/gpio/gpio-tps65910.c: In function 'tps65910_gpio_get': drivers/gpio/gpio-tps65910.c:31:2: error: implicit declaration of function 'tps65910_reg_read' [-Werror=implicit-function-declaration] 31 | tps65910_reg_read(tps65910, TPS65910_GPIO0 + offset, &val); | ^~~~~~~~~~~~~~~~~ drivers/gpio/gpio-tps65910.c: In function 'tps65910_gpio_set': drivers/gpio/gpio-tps65910.c:46:3: error: implicit declaration of function 'tps65910_reg_set_bits' [-Werror=implicit-function-declaration] 46 | tps65910_reg_set_bits(tps65910, TPS65910_GPIO0 + offset, | ^~~~~~~~~~~~~~~~~~~~~ drivers/gpio/gpio-tps65910.c:49:3: error: implicit declaration of function 'tps65910_reg_clear_bits' [-Werror=implicit-function-declaration] 49 | tps65910_reg_clear_bits(tps65910, TPS65910_GPIO0 + offset, | ^~~~~~~~~~~~~~~~~~~~~~~ Caused by commit 23feb2c3367c ("mfd: tps65910: Clean up after switching to regmap") I have used the version of the mfd tree from next-20201104 for today. -- Cheers, Stephen Rothwell
