Subject: [PATCH] r8152: Mark usb_ocp_read() as __maybe_unused
Date: Wed, 17 May 2017 15:20:56 -0700 [thread overview]
Message-ID: <20170517222056.183636-1-mka@chromium.org> (raw)
The function is not used, but is probably kept around for debugging and
symmetry with usb_ocp_write(). Adding the attribute fixes the following
clang warning:
drivers/net/usb/r8152.c:825:5: error: unused function 'usb_ocp_read'
[-Werror,-Wunused-function]
