When do coccicheck, I get this error:
spatch -D report --no-show-diff --very-quiet --cocci-file

minus: parse error:
File "./scripts/coccinelle/api/platform_get_irq.cocci", line 24, column 9, charpos = 355
around = '\(',
whole content = if ( ret \( < \| <= \) 0 )
In commit e56476897448 ("fpga: Remove dev_err() usage
after platform_get_irq()") log, I found the semantic patch,
it fix this issue.
Fixes: 98051ba2b2 ("coccinelle: Add script to check for platform_get_irq() excessive prints")
