Subject: [patch 34/39] sh: clkfwk: remove r8/r16/r32
Date: Fri, 14 Aug 2020 17:32:00 -0700 [thread overview]
Message-ID: <20200815003200.WlARhgLvU%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200814172939.55d6d80b6e21e4241f1ee1f3@linux-foundation.org>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
Subject: sh: clkfwk: remove r8/r16/r32
SH will get below warning
${LINUX}/drivers/sh/clk/cpg.c: In function 'r8':
${LINUX}/drivers/sh/clk/cpg.c:41:17: warning: passing argument 1 of 'ioread8'
discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
return ioread8(addr);
^~~~
In file included from ${LINUX}/arch/sh/include/asm/io.h:21,
from ${LINUX}/include/linux/io.h:13,
from ${LINUX}/drivers/sh/clk/cpg.c:14:
${LINUX}/include/asm-generic/iomap.h:29:29: note: expected 'void *' but
argument is of type 'const void *'
extern unsigned int ioread8(void __iomem *);
^~~~~~~~~~~~~~
We don't need "const" for r8/r16/r32. And we don't need r8/r16/r32
themselvs. This patch cleanup these.
