I found a bug in the part of interrupts.
In case there is a line like below in /proc/interrupts,
29: 0 0 0 0 0 0 0 0 IR-PCI-MSI-edge 0000:00:11.5
I expected the output will be as below.
29: ........ IR-PCI-MSI-edge 0000:00:11.5
But, actual output is as below.
29: ........ IR-PCI-MSI-edge▊
I checked the source code, and I found the regex is wrong.
According to the source code, it outputs the field as it is only in case the field contains alphabet.
But actually '.' or ':' can be located there, too.
So, I think the regex would be better to change [a-zA-Z] to [^0-9] like this PR.
Thank you.
