CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Bill Pemberton has done most of the legwork on this series. I've used his script to purge the attributes from the drivers/gpio tree.

The call sequence spi_alloc_master/spi_register_master/spi_unregister_master is complete; it reduces the device reference count to zero, which results in device memory being freed. An extra call to spi_master_put is unnecessary and results in an access to free memory. Drop it. Also, the device subsystem resets device driver data to NULL after the call to the remove function returns, so there is no need to do it here.

Trivial simplification. Instead of requiring spi master drivers to always set the bus number (even when a dynamic number is desired), this patch modifies spi_alloc_master() to initialize num_chipselect to 1 (because there will always be at least one CS) and bus_num to -1 for dynamic allocation. This simplifies the code needed to be written for drivers. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

We found that adding load, Rx data sometimes drops.(with DMA transfer mode) The cause is that before starting Rx-DMA processing, Tx-DMA processing starts. This causes FIFO overrun occurs. This patch fixes the issue by modifying FIFO tx-threshold and DMA descriptor size like below. Current this patch Rx-descriptor 4Byte+12Byte*341 --> 12Byte*340-4Byte-12Byte Rx-threshold (Not modified) Tx-descriptor 4Byte+12Byte*341 --> 16Byte-12Byte*340 Rx-threshold 12Byte --> 2Byte Signed-off-by: NTomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

This patch makes multiple cleanups to the new topcliff pch spi driver including, but not limited to, - removing superfluous brackets around variables - open coding functions that are only used once - removing unnecessary line breaks - removing unused functions - simplifying the interrupt enable/disable code - remove unnecessary (void *) casts. - remove b_mem_fail from pch_spi_set_tx to code it more cleanly - shorten dev_dbg() messages for conciseness and readability More cleanups are still needed in this driver. In particular, - the driver filename should be changed to spi_topcliff_pch.c - many of the dev_dbg() lines should be trimmed (particularly the ones on unconditional code paths). - I suspect that the locking model not correct. I'd like to know what drivers' critical regions are, and how they are protected. - get_resources and release_resources probably should be open coded in .probe and .release respectively.
