Subject: [PATCH 6.1 16/46] docs: perf: Fix PMU instance name of hisi-pcie-pmu
Date: Thu, 23 Feb 2023 14:06:23 +0100	[thread overview]
Message-ID: <20230223130432.302523447@linuxfoundation.org> (raw)
In-Reply-To: <20230223130431.553657459@linuxfoundation.org>

From: Yicong Yang <yangyicong@hisilicon.com>

[ Upstream commit eb79f12b4c41dd2403a0d16772ee72fcd6416015 ]

The PMU instance will be called hisi_pcie<sicl>_core<core> rather than
hisi_pcie<sicl>_<core>. Fix this in the documentation.

Fixes: c8602008e247 ("docs: perf: Add description for HiSilicon PCIe PMU driver")
