Revision 95fc2d8f96d37995f2bd1ec49f46ee9816ddf5b7 authored by Mike Frysinger on 28 March 2012, 03:43:02 UTC, committed by Bob Liu on 06 April 2012, 02:25:02 UTC
This patch fix below compile error: "bfin-uclinux-ld: L1 data A overflow!" It is due to the recent lib/gen_crc32table.c change: 46c5801eaf86e83cb3a4142ad35188db5011fff0 crc32: bolt on crc32c it added 8KiB more data to __cacheline_aligned which cause blackfin L1 data cache overflow.

/**
* mod_firmware_load - load sound driver firmware
* @fn: filename
* @fp: return for the buffer.
*
* Load the firmware for a sound module (up to 128K) into a buffer.
* The buffer is returned in *fp. It is allocated with vmalloc so is
* virtually linear and not DMAable. The caller should free it with
* vfree when finished.
*
* The length of the buffer is returned on a successful load, the
* value zero on a failure.
*
* Caution: This API is not recommended. Firmware should be loaded via
* request_firmware.
