patch "extcon: return error code on failure" added to char-misc-linus

This is a note to let you know that I've just added the patch titled

extcon: return error code on failure

to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: extcon: return error code on failure

Function get_zeroed_page() returns a NULL pointer if there is no enough memory. In function extcon_sync(), it returns 0 if the call to get_zeroed_page() fails. The return value 0 indicates success in the context, which is incosistent with the execution status. This patch fixes the bug by returning -ENOMEM.
