TIMEOUT after 1554m


Sorry we cannot finish the testset for your branch within a reasonable time.
It's our fault -- either some build server is down or some build worker is busy
doing bisects for _other_ trees. The branch will get more complete coverage and
possible error reports when our build infrastructure is restored or catches up.
There will be no more build success notification for this branch head, but you
can expect reasonably good test coverage after waiting for 1 day.

[PATCH] media: omap2: omapfb: fix bugon.cocci warnings

[kbuild test robot]

From: kbuild test robot 

drivers/video/fbdev/omap2/omapfb/dss/dss_features.c:895:2-5: WARNING: Use 
BUG_ON instead of if condition followed by BUG.
Please make sure the condition has no side effects (see conditional BUG_ON 
definition in include/asm-generic/bug.h)

 Use BUG_ON instead of a if condition followed by BUG.

Semantic patch information:
 This makes an effort to find cases where BUG() follows an if
 condition on an expression and replaces the if condition and BUG()
 with a BUG_ON having the conditional expression of the if statement
 as argument.

Generated by: scripts/coccinelle/misc/bugon.cocci

Fixes: 7378f1149884 ("media: omap2: omapfb: allow building it with 
COMPILE_TEST")

Please take the patch only if it's a positive warning. Thanks!

[ragnatech:media-tree] BUILD INCOMPLETE 231783073ebfc4acf02a45cb78a52ffa16e4e6d3

[kbuild test robot]

tree/branch: git://git.ragnatech.se/linux  media-tree
branch HEAD: 231783073ebfc4acf02a45cb78a52ffa16e4e6d3  media: v4l: rcar_fdp1: 
Enable compilation on Gen2 platforms

TIMEOUT after 600m


Sorry we cannot finish the testset for your branch within a reasonable time.
It's our fault -- either some build server is down or some build worker is busy
doing bisects for _other_ trees. The branch will get more complete coverage and
possible error reports when our build infrastructure is restored or catches up.
There will be no more build success notification for this branch head, but you
can expect reasonably good test coverage after waiting for 1 day.
