Subject: [PATCH 2/3 RFC] ath10k: wmi: match wait_for_completion_timeout return type
Date: Thu, 12 Mar 2015 11:49:22 -0400 [thread overview]
Message-ID: <1426175362-8640-1-git-send-email-hofrat@osadl.org> (raw)
Return type of wait_for_completion_timeout is unsigned long not int.
An appropriately named unsigned long is added and the assignments fixed up.
Rather than returning 0 (timeout) or a more or less random remaining time
(completion success) this return 0 or 1 which also resolves the type of the
functions being int.
Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>

Checking the call-sites of ath10k_wmi_wait_for_unified_ready and
ath10k_wmi_wait_for_service_ready the positive return value (remaining
time in jiffies) is never passed up the call-chain nor used so it is
cleaner to treat this like a boolean success/fail only (actually the two
functions should probably be of type bool - but that does not seem to be
common practice in the ath10k code base)
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-20150312)
