The dev field is remove from struct regulator_consumer_supply since commit 737f36 "regulator: Remove support for supplies specified by struct device". This fixes below build error: CC arch/arm/mach-u300/i2c.o arch/arm/mach-u300/i2c.c:63: error: unknown field 'dev' specified in initializer arch/arm/mach-u300/i2c.c:95: error: unknown field 'dev' specified in initializer make[1]: *** [arch/arm/mach-u300/i2c.o] Error 1 make: *** [arch/arm/mach-u300] Error 2 Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
