Subject: [PATCH 08/10] staging: rtl8188eu: remove constant function parameter
Date: Sun, 18 Jul 2021 19:36:08 +0200	[thread overview]
Message-ID: <20210718173610.894-8-martin@kaiser.cx> (raw)
In-Reply-To: <20210718173610.894-1-martin@kaiser.cx>

The rtl88eu_pwrseqcmdparsing function takes a parameter to restrict
commands to certain power cut versions of the rtl8188eu chipset.
This mechanism is not used, the callers always select all versions.

Remove the power cut parameter.
