Subject: linux-next: build warning after merge of the mmc-uh tree
Date: Mon, 6 Jun 2016 11:38:48 +1000 [thread overview]
Message-ID: <20160606113848.534cbdf7@canb.auug.org.au> (raw)
Hi Ulf,
After merging the mmc-uh tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
In file included from include/linux/err.h:4:0,
from drivers/mmc/core/mmc.c:13:
drivers/mmc/core/mmc.c: In function 'mmc_select_hs400es':
include/linux/err.h:21:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
#define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO)
^
include/linux/compiler.h:170:42: note: in definition of macro 'unlikely'
# define unlikely(x) __builtin_expect(!!(x), 0)
^
drivers/mmc/core/mmc.c:1244:6: note: in expansion of macro 'IS_ERR_VALUE'
if (IS_ERR_VALUE(err))
^
Introduced by commit
8141f0ace818 ("mmc: core: implement enhanced strobe support")
I think error values now must be "long".

Cheers,
