Subject: [PATCH 3/3 v2] sh: fix READ/WRITE redefinition warnings
Date: Sun, 27 Jun 2021 15:05:44 -0700 [thread overview]
Message-ID: <20210627220544.8757-4-rdunlap@infradead.org> (raw)
In-Reply-To: <20210627220544.8757-1-rdunlap@infradead.org>
kernel.h defines READ and WRITE, so rename the SH math-emu macros
to MREAD and MWRITE.
Fixes these warnings:
../arch/sh/math-emu/math.c:54: warning: "WRITE" redefined
54 | #define WRITE(d,a) ({if(put_user(d, (typeof (d) __user *)a)) return -EFAULT;})
In file included from ../arch/sh/math-emu/math.c:10:
../include/linux/kernel.h:37: note: this is the location of the previous definition
37 | #define WRITE 1
../arch/sh/math-emu/math.c:55: warning: "READ" redefined
55 | #define READ(d,a) ({if(get_user(d, (typeof (d) __user *)a)) return -EFAULT;})
In file included from ../arch/sh/math-emu/math.c:10:
../include/linux/kernel.h:36: note: this is the location of the previous definition
36 | #define READ 0
Fixes: 4b565680d163 ("sh: math-emu support")
