Subject: [PATCH v2 2/6] net: ethernet: bgmac: add dma_dev pointer
Date: Thu, 7 Jul 2016 19:08:54 -0400 [thread overview]
Message-ID: <1467932938-21819-3-git-send-email-jon.mason@broadcom.com> (raw)
In-Reply-To: <1467932938-21819-1-git-send-email-jon.mason@broadcom.com>
The dma buffer allocation, etc references a dma_dev device pointer from
the bcma core. In anticipation of removing the bcma requirement for
this driver, these must be changed to not reference that struct. Add a
dma_dev device pointer to the bgmac stuct and reference that instead.
