Subject: [PATCH 14/16] wil6210: remove unnecessary alignment code from rx flow
Date: Wed, 31 Oct 2018 10:52:22 +0200	[thread overview]
Message-ID: <1540975944-30576-15-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1540975944-30576-1-git-send-email-merez@codeaurora.org>

From: Ahmad Masri <amasri@codeaurora.org>

Rx buffers in EDMA mode are initialized to 4 bytes aligned size.
Remove the unnecessary alignment code applied on rx buffer size.
