Subject: [ 35/47] efivars: fix warnings when CONFIG_PSTORE=n

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tony Luck <tony.luck@...el.com>

commit b728a5c806fb36f9adebf2a862bbd015e074afca upstream.

drivers/firmware/efivars.c:161: warning: ‘utf16_strlen’ defined but not used
utf16_strlen() is only used inside CONFIG_PSTORE - make this "static inline"
to shut the compiler up [thanks to hpa for the suggestion].

drivers/firmware/efivars.c:602: warning: initialization from incompatible pointer type
Between v1 and v2 of this patch series we decided to make the "part" number
unsigned - but missed fixing the stub version of efi_pstore_write()

[took the static part of the patch, not the pstore part, for 3.0-stable,
to fix the compiler warning we had - gregkh]
