Subject: [PATCH net-next 2/2] mvpp2: suppress warning
Date: Mon, 10 May 2021 18:52:32 +0200	[thread overview]
Message-ID: <20210510165232.16609-3-mcroce@linux.microsoft.com> (raw)
In-Reply-To: <20210510165232.16609-1-mcroce@linux.microsoft.com>

From: Matteo Croce <mcroce@microsoft.com>

Remove some unreachable code, so to suppress this warning:

drivers/net/ethernet/marvell/mvpp2/mvpp2_prs.c: In function ‘mvpp2_prs_tcam_first_free’:
drivers/net/ethernet/marvell/mvpp2/mvpp2_prs.c:397:10: warning: comparison is always false due to limited range of data type [-Wtype-limits]
  397 |  if (end >= MVPP2_PRS_TCAM_SRAM_SIZE)
      |          ^~

Fixes: 3f518509dedc ("ethernet: Add new driver for Marvell Armada 375 network unit")
