Subject: ARM: versatile: Remove IRQF_ONESHOT
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a82bf786500a011c0ecc63ce1511b7fc471137cd;p=thirdparty%2Fkernel%2Flinux.git

ARM: versatile: Remove IRQF_ONESHOT

Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.

Revert adding IRQF_ONESHOT to irqflags.
