Linus Torvalds 3837f9a08b TTY / Serial driver fixes for 5.13-rc4 
Here are some small fixes for reported problems for tty and serial
 drivers for 5.13-rc4.
 
 They consist of:
 	- 8250 bugfixes and new device support
 	- lockdown security mode fixup
 	- syzbot found problems fixed
 	- 8250_omap fix for interrupt storm
 	- revert of 8250_omap driver fix as it caused worse problem than
 	  the original issue
 
 All but the last patch have been in linux-next for a while, the last one
 is a revert of a problem found in linux-next with the 8250_omap driver
 change.
