[PATCH] [v2] wilc1000: Fix memleak in wilc_sdio_probe
From: Dinghao Liu <hidden>
Date: 2020-08-20 05:48:49
Also in:
linux-wireless, lkml
Subsystem:
microchip wilc1000 wifi driver, the rest · Maintainers:
Ajay Singh, Claudiu Beznea, Linus Torvalds
When devm_clk_get() returns -EPROBE_DEFER, sdio_priv
should be freed just like when wilc_cfg80211_init()
fails.
Fixes: 8692b047e86cf ("staging: wilc1000: look for rtc_clk clock")
Signed-off-by: Dinghao Liu <redacted>

Changelog:
v2: - Remove 'staging' prefix in subject.
