Subject: [PATCH 4.16 173/279] IB/hfi1 Use correct type for num_user_context
4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Michael J. Ruhl" <michael.j.ruhl@...el.com>
[ Upstream commit 5da9e742be44d9b7c68b1bf6e1aaf46a1aa7a52b ]
The module parameter num_user_context is defined as 'int' and
defaults to -1. The module_param_named() says that it is uint.
Correct module_param_named() type information and update the modinfo
text to reflect the default value.
