Message-Id: <20170304085623.32674-1-ernestas.kulik@gmail.com>
Date: Sat, 4 Mar 2017 10:56:23 +0200
From: Ernestas Kulik <ernestas.kulik@...il.com>
To: gregkh@...uxfoundation.org
Cc: devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org
Subject: [PATCH v2] staging: ks7010: fix sparse warnings
Currently, sparse generates many warnings for the driver. This commit
changes the types of struct fields/function variables to match the
endianness at their assignment.
Signed-off-by: Ernestas Kulik <ernestas.kulik@...il.com>
---
Changes from v1:
* Change the type of the variable being passed to ntohs() instead of casting it
* Don’t remove any struct fields
