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

serial: 8250: 8250_omap: Fix RX_LVL register offset

to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-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.

From: Nishanth Menon nm@ti.com Date: Fri, 3 Sep 2021 00:05:50 -0500 Subject: serial: 8250: 8250_omap: Fix RX_LVL register offset

Commit b67e830d38fa ("serial: 8250: 8250_omap: Fix possible interrupt storm on K3 SoCs") introduced fixup including a register read to RX_LVL, however, we should be using word offset than byte offset since our registers are on 4 byte boundary (port.regshift = 2) for 8250_omap.
