The first patch adds an error message so that any others that are discovered in the future are easier to diagnose (this one took a while to reproduce and identify). Zev Weiss (3): aspeed-video: add error message for unhandled interrupts aspeed-video: clear spurious interrupt bits unconditionally aspeed-video: add COMP_READY to VE_SPURIOUS_IRQS drivers/media/platform/aspeed-video.c | 25 ++++++++++++++++--------- 1 file changed, 16 insertions(+), 9 deletions(-)
