X-Git-Tag: upstream/snapshot3+hdmi~5807^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0fafd50e4b41c06bf6be8dead87075e88ef25303;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

pinctrl: nomadik: nmk_prcm_gpiocr_get_mode may be unused

nmk_prcm_gpiocr_get_mode is only needed for debugfs output at
the moment, which can be compile-time disabled. Marking
the function __maybe_unused still gives us compile-time
coverage, but avoids a gcc warning.

Without this patch, building nhk8815_defconfig results in:

drivers/pinctrl/pinctrl-nomadik.c:676:12: warning: 'nmk_prcm_gpiocr_get_mode' defined but not used [-Wunused-function]
