Subject: fbdev: omap: pass irqs as resource
X-Git-Tag: v6.6.17~7441^2~10^2~32
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=81ad0f5bc476505781b1398be52a81eda3ee9798;p=platform%2Fkernel%2Flinux-rpi.git

fbdev: omap: pass irqs as resource

To avoid relying on the mach/irqs.h header, stop using
OMAP_LCDC_IRQ and INT_1610_SoSSI_MATCH directly in the driver
code, but instead pass these as resources.
