Subject: [PATCH 04/18] brcmfmac: remove unused struct brcmf_sdio_dev::func_cis_ptr attribute
Date: Thu, 12 Dec 2013 11:58:52 +0100	[thread overview]
Message-ID: <1386845946-9859-5-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1386845946-9859-1-git-send-email-arend@broadcom.com>

During the SDIO probe the func_cis_ptr attribute in struct brcmf_sdio_dev
is being determined, but it is never used after that. Removing it also
obsoletes two functions in bcmsdh.c.
