Subsystems (3)
This is a note to let you know that I've just added the patch titled
usb: musb: tusb6010: uninitialized data in
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-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.

tusb_fifo_write_unaligned()
This is writing to the first 1 - 3 bytes of "val" and then writing all four bytes to musb_writel(). The last byte is always going to be garbage. Zero out the last bytes instead.
