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-testing 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 be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

According to the Spreadtrum eFuse specification, we should write 0 to the block to trigger the lock operation.
