m68k build regression
Hi, starting from 3.9-rc1 one of my m68k configurations does not build, which is a regression. The configuration is attached. I build with W=1. I did not look at the details, just shooting a bug report. drivers/gpio/devres.c: In function 'devm_gpio_request_one': drivers/gpio/devres.c:90:2: error: implicit declaration of function 'gpio_request_one' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[3]: *** [drivers/gpio/devres.o] Error 1 Thanks! -- Best Regards, Artem Bityutskiy - Intel Finland Oy Registered Address: PL 281, 00181 Helsinki Business Identity Code: 0357606 - 4 Domiciled in Helsinki This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

So to use the devres facility arch/m68k/include/asm/gpio.h needs to provide gpio_request_one(). Which it doesn't and thus fails. Did some driver you're using start to use devm_gpio_request_one() recently? I vaguely remember Alexandre looking into things like this so adding him...

I know OpenRisc had an issue with devres.c (CC Jonas), please look at commit d4cb776f for the fix. I don't think my changes for 3.9 are responsible for this, they only deal with gpiolib's internals and not with header files, so they should be noop for platforms only using GENERIC_GPIO. I'd recommend doing the same as OpenRisc (turning GENERIC_GPIO and ARCH_WANT_OPTIONAL_GPIOLIB into ARCH_REQUIRE_GPIOLIB), anyway GENERIC_GPIO is being removed for 3.10, so you better get used to using gpiolib from now on. :) Alex. --- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
