Wed May 3 09:00:25 UTC 2023
The following checkpatch errors & warning is removed.
ERROR: else should follow close brace '}'
ERROR: trailing statements should be on next line
WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
WARNING: Possible repeated word: 'Fences'
WARNING: Missing a blank line after declarations
WARNING: braces {} are not necessary for single statement blocks
WARNING: Comparisons should place the constant on the right side of the test
WARNING: printk() should include KERN_<LEVEL> facility level

v2:
- Best to make the word "Fences" one line from that. E.g. "/* Fences mark an
event...". (Christian)
