Subject: [PATCH v2,0/5] drivers: uio: new driver uio_fsl_85xx_cache_sram

This series add a new uio driver for freescale 85xx platforms to
access the Cache-Sram form user level. This is extremely helpful
for the user-space applications that require high performance memory
accesses.

It fixes the compile errors and warning of the hardware level drivers
and implements the uio driver in uio_fsl_85xx_cache_sram.c.

Changes since v1:
 * Addressed comments of Greg K-H
 * Moved kfree(info->name) into uio_info_free_internal()
