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

nvmem: qfprom: remove incorrect write support

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 (usually sometime within the next 24 hours during the week.)

The patch will also be merged in the next major kernel release during the merge window.

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

qfprom has different address spaces for read and write. Reads are always done from corrected address space, where as writes are done on raw address space. Writing to corrected address space is invalid and ignored, so it does not make sense to have this support in the driver which only supports corrected address space regions at the moment.
