Subject: [PATCH] fb: via: turn gpiolib and i2c selects into dependencies
Date: Wed, 28 Jan 2015 20:12:33 +0000 [thread overview]
Message-ID: <3127720.VGEDzudcPs@wuerfel> (raw)
Device driver should not directly select subsystems. In this case
we get build warnings like
warning: (ARCH_REQUIRE_GPIOLIB && PINCTRL_AT91 && PINCTRL_NOMADIK && MFD_TC6393XB && FB_VIA) selects GPIOLIB which has unmet direct dependencies (ARCH_WANT_OPTIONAL_GPIOLIB || ARCH_REQUIRE_GPIOLIB)
which we can avoid using the normal 'depends on' statement.
Also, this patch makes it possible for DRM drivers to have a dependency
on GPIOLIB without getting circular Kconfig dependencies.
