| |
return type of wait_for_completion_timeout is unsigned long not int, this patch uses the return value of wait_for_completion_timeout in the condition directly rather than assigning it to an incorrect type variable.
Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> ---
The return type of wait_for_completion_timeout is unsigned long not int. This patch resolves the type mismatch by moving the call to wait_for_completion_timeout into the condition.
This patch was only compile tested with omap2plus_defconfig
Patch is against 3.19.0-rc6 -next-20150130
