Revision d34c1fcddc3a159d52576c656f8caabc0cf4894b authored by Wolfram Sang on 08 July 2011, 09:16:56 UTC, committed by Kukjin Kim on 08 July 2011, 09:16:56 UTC
If mini2440_init() is in __init, mini2440_parse_features() should also be in __init. Fixes: (.text+0x9adc): Section mismatch in reference from the function mini2440_parse_features.clone.0() to the (unknown reference) .init.data:(unknown) The function mini2440_parse_features.clone.0() references the (unknown reference) __initdata (unknown).

/**
* 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.
