Return type of wait_for_completion_timeout is unsigned long not int. An appropriately named unsigned long is added, respectively 'ret' renamed, and the assignments fixed up. Signed-off-by: Nicholas Mc Guire <redacted> --- Patch was only compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m, CONFIG_ATH10K=m Patch is against 4.0-rc3 (localversion-next is -next-20150313) drivers/net/wireless/ath/ath10k/mac.c | 20 +++++++++++--------- 1 file changed, 11 insertions(+), 9 deletions(-)
