[PATCH] video: pxa3xx-gcu: Simplify the logic to exit while loop in pxa3xx_gcu_wait_idle
From: Axel Lin <hidden>

If wait_event_interruptible_timeout returns a positive value, it means the condition evaluated is true. Which means priv->shared->hw_running is false. And then we will exit the loop. This patch simplifies the logic to exit the while loop. Signed-off-by: Axel Lin <redacted> --- drivers/video/pxa3xx-gcu.c | 5 +---- 1 files changed, 1 insertions(+), 4 deletions(-)
