[PATCH AUTOSEL 5.14 13/18] cavium: Fix return values of the probe function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Zheyu Ma <zheyuma97@xxxxxxxxx>

[ Upstream commit c69b2f46876825c726bd8a97c7fa852d8932bc32 ]

During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
