YueHaibing ca7ce5a271 coccinelle: platform_get_irq: Fix parse error 
When do coccicheck, I get this error:

spatch -D report --no-show-diff --very-quiet --cocci-file
./scripts/coccinelle/api/platform_get_irq.cocci --include-headers
--dir . -I ./arch/x86/include -I ./arch/x86/include/generated -I ./include

 --include ./include/linux/kconfig.h --jobs 192 --chunksize 1
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.

Stephen Boyd 98051ba2b2 coccinelle: Add script to check for platform_get_irq() excessive prints 
Add a coccinelle script to check for the usage of dev_err() after a call
to platform_get_irq{,_byname}() as it's redundant now that the function
already prints an error when it fails.
