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,
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]

Introduced by commit

I think error values now must be "long".
