[U-Boot] [PATCH v2] drivers: mmc: Change buffer type in ALLOC_CACHE_ALIGN_BUFFER macro

[sunil.m at techveda.org <sunil.m@techveda.org>]

From: Suniel Mahesh <sunil.m@techveda.org>

__be32_to_cpu() accepts argument of type __be32. This patch changes
type of the buffer in ALLOC_CACHE_ALIGN_BUFFER macro to __be32, which
is then passed to __be32_to_cpu().
This prevents sparse build warnings.
drivers/mmc/mmc.c: warning: cast to restricted __be32
