Subject: [PATCH 3/9] staging: media: atomisp: annotate an unused function
Date: Fri, 29 May 2020 22:00:25 +0200 [thread overview]
Message-ID: <20200529200031.4117841-3-arnd@arndb.de> (raw)
In-Reply-To: <20200529200031.4117841-1-arnd@arndb.de>
atomisp_mrfld_power() has no more callers and produces
a warning:
drivers/staging/media/atomisp/pci/atomisp_v4l2.c:764:12: error: unused function 'atomisp_mrfld_power' [-Werror,-Wunused-function]
Mark the function as unused while the PM code is being
debugged, expecting that it will be used again in the
future and should not just be removed.
Fixes: 95d1f398c4dc ("media: atomisp: keep the ISP powered on when setting it")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
