Subject: [PATCH AUTOSEL 4.4 25/33] brcmsmac: fix memory leak in wlc_phy_attach_lcnphy
Date: Sun, 18 Oct 2020 15:27:20 -0400 [thread overview]
Message-ID: <20201018192728.4056577-25-sashal@kernel.org> (raw)
In-Reply-To: <20201018192728.4056577-1-sashal@kernel.org>
From: Keita Suzuki <keitasuzuki.park@sslab.ics.keio.ac.jp>
[ Upstream commit f4443293d741d1776b86ed1dd8c4e4285d0775fc ]
When wlc_phy_txpwr_srom_read_lcnphy fails in wlc_phy_attach_lcnphy,
the allocated pi->u.pi_lcnphy is leaked, since struct brcms_phy will be
freed in the caller function.
Fix this by calling wlc_phy_detach_lcnphy in the error handler of
wlc_phy_txpwr_srom_read_lcnphy before returning.
