Subject: [PATCH 4/6] staging: rtl8188eu: remove padapter from struct cmd_priv
Date: Wed,  5 May 2021 22:26:20 +0200	[thread overview]
Message-ID: <20210505202622.11087-4-martin@kaiser.cx> (raw)
In-Reply-To: <20210505202622.11087-1-martin@kaiser.cx>

struct cmd_priv is an element of struct adapter. Use container_of
to get a pointer to the enclosing struct.
