Subject: [PATCH AUTOSEL 4.9 71/99] ntb: intel: fix return value for ndev_vec_mask()
Date: Sat, 16 Nov 2019 10:50:34 -0500	[thread overview]
Message-ID: <20191116155103.10971-71-sashal@kernel.org> (raw)
In-Reply-To: <20191116155103.10971-1-sashal@kernel.org>

From: Dave Jiang <dave.jiang@intel.com>

[ Upstream commit 7756e2b5d68c36e170a111dceea22f7365f83256 ]

ndev_vec_mask() should be returning u64 mask value instead of int.
Otherwise the mask value returned can be incorrect for larger
vectors.

Fixes: e26a5843f7f5 ("NTB: Split ntb_hw_intel and ntb_transport drivers")
