Subject: [PATCH] udev: builtin-keyboard: move actual key mapping to a helper
ecbff1
 function
ecbff1
ecbff1
No changes in the mapping, but previously we opened the device only on
ecbff1
successful parsing. Now we open the mapping as soon as we have a value that
ecbff1
looks interesting. Since errors are supposed to be the exception, not the
ecbff1
rule, this is probably fine.

ecbff1
(cherry picked from commit c9a8e34094733018727677fee44be2c2952224c0)
ecbff1
ecbff1
Resolves: #1500119
