| |
From: Valentin Rothberg <valentinrothberg@gmail.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 90adf98d9530054b8e665ba5a928de4307231d84 upstream.
Since commit 1c6c69525b40 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail.
scripts/coccinelle/misc/irqf_oneshot.cocci detected this issue.
