Subject: [PATCH] sh: clk: Fix discarding const qualifier warning
Date: Tue, 7 Jan 2020 13:26:03 +0100 [thread overview]
Message-ID: <1578399963-2229-1-git-send-email-krzk@kernel.org> (raw)
ioreadX() accepts pointer to non-const memory. This fixes warnings
like:
drivers/sh/clk/cpg.c: In function ‘r8’:
drivers/sh/clk/cpg.c:41:17: warning: passing argument 1 of ‘ioread8’
discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
