Subject: [PATCH 2/2] ath10k: pci: remove unnecessary casts
Date: Thu, 27 Jun 2019 21:47:30 +0300 [thread overview]
Message-ID: <1561661250-30528-2-git-send-email-kvalo@codeaurora.org> (raw)
In-Reply-To: <1561661250-30528-1-git-send-email-kvalo@codeaurora.org>
Fixes checkpatch warnings:
drivers/net/wireless/ath/ath10k/pci.c:926: unnecessary cast may hide bugs, see http://c-faq.com/malloc/ma
drivers/net/wireless/ath/ath10k/pci.c:1072: unnecessary cast may hide bugs, see http://c-faq.com/malloc/m
While at it, also remove unnecessary initialisation of data_buf variable in both cases.
