Subject: [PATCH] mt7601u: fix bbp version check in mt7601u_wait_bbp_ready
Git-commit: 15e14f76f85f4f0eab3b8146e1cd3c58ce272823
Patch-mainline: v5.5-rc1
References: bsc#1051510
Fix bbp ready check in mt7601u_wait_bbp_ready. The issue is reported by
coverity with the following error:
Logical vs. bitwise operator
The expression's value does not depend on the operands; inadvertent use
of the wrong operator is a likely logic error.

Fixes: c869f77d6abb ("add mt7601u driver")
