Subject: [PATCH AUTOSEL 5.5 222/542] Revert "tty/serial: atmel: fix out of range clock divider handling"

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

[ Upstream commit 6dbd54e4154dfe386b3333687de15be239576617 ]

This reverts commit 751d0017334db9c4d68a8909c59f662a6ecbcec6.

The wrong commit got added to the tty-next tree, the correct one is in
the tty-linus branch.
