[Bug 1901089] [NEW] Ubuntu kernels 5.4.0-51 and 5.4.0-52 break ir-keytable loading

Public bug reported:

I run mythtv on Ubuntu 20.04 and I used a custom remote control keymap
in /etc/rc_keymaps to correctly map buttons on my IR remote. The above
kernel seems to break custom keymap loading for my remote (certain
buttons no longer work in mythtv). Reverting to kernel 5.4.0-48
corrects the problem.
