Subject: [PATCH 4.19 17/36] cxgb4: use correct type for all-mask IP address comparison
Date: Tue,  7 Jul 2020 17:17:09 +0200	[thread overview]
Message-ID: <20200707145749.959174058@linuxfoundation.org> (raw)
In-Reply-To: <20200707145749.130272978@linuxfoundation.org>

From: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com>

[ Upstream commit f286dd8eaad5a2758750f407ab079298e0bcc8a5 ]

Use correct type to check for all-mask exact match IP addresses.

Fixes following sparse warnings due to big endian value checks
against 0xffffffff in is_addr_all_mask():
cxgb4_filter.c:977:25: warning: restricted __be32 degrades to integer
cxgb4_filter.c:983:37: warning: restricted __be32 degrades to integer
cxgb4_filter.c:984:37: warning: restricted __be32 degrades to integer
cxgb4_filter.c:985:37: warning: restricted __be32 degrades to integer
cxgb4_filter.c:986:37: warning: restricted __be32 degrades to integer

Fixes: 3eb8b62d5a26 ("cxgb4: add support to create hash-filters via tc-flower offload")
