[PATCH AUTOSEL 5.14 30/32] NTB: perf: Fix an error code in perf_setup_inbuf()

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

 



From: Yang Li <yang.lee@xxxxxxxxxxxxxxxxx>

[ Upstream commit 0097ae5f7af5684f961a5f803ff7ad3e6f933668 ]

When the function IS_ALIGNED() returns false, the value of ret is 0.
So, we set ret to -EINVAL to indicate this error.

Clean up smatch warning:
drivers/ntb/test/ntb_perf.c:602 perf_setup_inbuf() warn: missing error
code 'ret'.
