Subject: nvmem: include linux/err.h from header
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=42a6e0996084972574e0a2b23e7326b78b0f64c5;p=linux.git

nvmem: include linux/err.h from header

The new support for nvmem devices from the rtc layer caused a build
error in some configurations:

include/linux/nvmem-provider.h: In function 'nvmem_register':
include/linux/nvmem-provider.h:51:9: error: implicit declaration of function 'ERR_PTR' [-Werror=implicit-function-declaration]

This adds the missing include to ensure we can always include
the header.
