This is a note to let you know that I've just added the patch titled
nvmem: sprd: Fix the block lock operation
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-next branch.
The patch will show up in the next release of the linux-next tree
