Subject[PATCH v4] clocksource/drivers/timer-cs5535: request irq with non-NULL dev_id
Date
Recently all usages of setup_irq() was replaced by request_irq().
request_irq() does a few sanity checks that were not done in
setup_irq(), if they fail irq registration will fail. One of the check
is to ensure that non-NULL dev_id is passed in the case of shared irq.

Fix it by passing non-NULL dev_id while registering the shared irq.

Fixes: cc2550b421aa ("clocksource: Replace setup_irq() by request_irq()")

Hi Daniel,

i have assumed that you would not rebase your drivers/next tree & put the
SHA-id in Fixes tag.

Regards
afzal
