Hi Stable folks,

please apply commit 27ed14d0ecb38516b6f3c6fdcd62c25c9454f979 Revert "serial/8250: Add support for NI-Serial PXI/PXIe+485 devices" also to the stable tree.

My Fedora cannot switch baudrate or write to my serial port and that makes me so sad.

I have this problem with kernel v5.6.11.

Hey Linus,

Are you sure about the commit? 27ed14d0ecb3 ("Revert "serial/8250: Add support for NI-Serial PXI/PXIe+485 devices"") was merged upstream in v5.5.

Sorry I got the wrong one, I need to do some more bisecting and find the real problem... :/

Yours, Linus Walleij
