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

USB: storage: add quirk for SMI SM3350

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.

The SMI SM3350 USB-UFS bridge controller cannot handle long sense request correctly and will make the chip refuse to do read/write when requested long sense.

Add a bad sense quirk for it.
