Subject: jsm: IRQ handlers doesn't need to have IRQ_DISABLED enabled
X-Git-Tag: accepted/tizen/common/20141203.182822~13518^2~57
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a88a477f1df703f0e2a7592e19618799cb598623;p=platform%2Fkernel%2Flinux-arm64.git

jsm: IRQ handlers doesn't need to have IRQ_DISABLED enabled

Currently jsm is showing the following message when loaded:

IRQ 432/JSM: IRQF_DISABLED is not guaranteed on shared IRQs

It's because the request_irq() is called using IRQF_DISABLED
and IRQF_SHARED.
Actually there is no need to use IRQF_DISABLED in this driver.
