[PATCH 5.13 248/300] ath6kl: wmi: fix an error code in ath6kl_wmi_sync_point()

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

 



From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit fd6729ec534cffbbeb3917761e6d1fe6a412d3fe ]

This error path is unlikely because of it checked for NULL and
returned -ENOMEM earlier in the function.  But it should return
an error code here as well if we ever do hit it because of a
race condition or something.
