Subject: [PATCH v2 09/11] clk: fix incorrect usage of ENOSYS
Date: Sun, 21 May 2017 23:59:56 +0200 [thread overview]
Message-ID: <20170521215958.19743-10-jbrunet@baylibre.com> (raw)
In-Reply-To: <20170521215958.19743-1-jbrunet@baylibre.com>
ENOSYS is special and should only be used for incorrect syscall number.
It does not seem to be the case here.
Reported by checkpatch.pl while working on clock protection.
