From: Alex Vesker Date: Thu, 13 Jul 2017 08:27:12 +0000 (+0300) Subject: IB/ipoib: Prevent setting negative values to max_nonsrq_conn_qp X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11f74b40359b19f760964e71d04882a6caf530cc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git IB/ipoib: Prevent setting negative values to max_nonsrq_conn_qp Don't allow negative values to max_nonsrq_conn_qp. There is no functional impact on a negative value but it is logicically incorrect.
