Subject: [PATCH 07/15] mmc: sdhci: Use 'void *' for not 'u8 *' for ADMA data
Date: Tue, 21 Oct 2014 12:26:17 +0300	[thread overview]
Message-ID: <1413883585-16299-8-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1413883585-16299-1-git-send-email-adrian.hunter@intel.com>

It is kernel-style to use 'void *' for anonymous data.
This is being applied to the ADMA bounce buffer which
contains unaligned bytes, and to the ADMA descriptor
table which will contain 32-bit ADMA descriptors
or 64-bit ADMA descriptors when support is added.
