linux-wireless, lkml
Subsystem:
microchip wilc1000 wifi driver, the rest · Maintainers:
Ajay Singh, Claudiu Beznea, Linus Torvalds
Status: Landed in mainline as d8eb176d97d3 on 2020-08-28.
When devm_clk_get() returns -EPROBE_DEFER, spi_priv
should be freed just like when wilc_cfg80211_init()
fails.
Fixes: 854d66df74aed ("staging: wilc1000: look for rtc_clk clock in spi mode")
