fbdev: au1200fb: Fix missing IRQ check in au1200fb_drv_probe
[ Upstream commit 4e88761f ] This func misses checking for platform_get_irq()'s call and may passes the negative error codes to request_irq(), which takes unsigned IRQ #, causing it to fail with -EINVAL, overriding an original error code. Fix this by stop calling request_irq() with invalid IRQ #s. Fixes: 1630d85a ("au1200fb: fix hardcoded IRQ") Signed-off-by:Zhang Shurong <zhang_shurong@foxmail.com> Signed-off-by:
