Subject: drivers/pcmcia/m32r_pcc.c: check return from request_irq
While building m32r allmodconfig we were getting warning:
drivers/pcmcia/m32r_pcc.c:331:2:
warning: ignoring return value of 'request_irq',
declared with attribute warn_unused_result
request_irq() can fail and we should always be checking the result from
it. Check the result and return it to the caller.
