Subject: [PATCH 1/4] riscv: drop cpufeature_apply_feature tracking variable
Date: Wed, 18 May 2022 19:02:51 +0200	[thread overview]
Message-ID: <20220518170254.3178923-2-heiko@sntech.de> (raw)
In-Reply-To: <20220518170254.3178923-1-heiko@sntech.de>

The variable was tracking which feature patches got applied
but that information was never actually used - and thus resulted
in a warning as well.

Drop the variable.
