Message-Id: <1508907329-1077-2-git-send-email-subashab@codeaurora.org>
Date: Tue, 24 Oct 2017 22:55:26 -0600
From: Subash Abhinov Kasiviswanathan <subashab@...eaurora.org>

Cc: Subash Abhinov Kasiviswanathan <subashab@...eaurora.org>
Subject: [PATCH net-next 1/4] net: qualcomm: rmnet: Fix the return value of rmnet_rx_handler()
Since packet is always consumed by rmnet_rx_handler(), we always
return RX_HANDLER_CONSUMED. There is no need to pass on this
value through multiple functions.
