[PATCH 3.16.y-ckt 101/126] ALSA: fireworks: use u32 type for be32_to_cpup() macro

From: Luis Henriques
Date: Wed Dec 09 2015 - 04:41:42 EST

3.16.7-ckt21 -stable review patch. If anyone has any objections, please let me know.


From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>

commit 463543ac2effaeb2b524f0a0a92f2413c23998ca upstream.

In former commit, snd_efw_command_get_phys_meters() was added to handle
metering data. The given buffer is used to save transaction result and to
convert between endianness. But this causes sparse warnings.

fireworks_command.c:269:25: warning: incorrect type in argument 1 (different base types)
fireworks_command.c:269:25: expected unsigned int [usertype] *p
fireworks_command.c:269:25: got restricted __be32 [usertype] *

This commit fixes this bug.
