2013-12-02spi: omap-100k: remove pointless _remove functionMichal Nazarewicz1-20/+0
Commit [8074cf06: use devm_spi_register_master()] removed the last bit of omap1_spi100k_remove function that had side effects. After call to spi_unregister_master was removed, the function consisted of: 2. call to platform_get_drvdata whose return value was only used in: 2. call to spi_master_get_devdata whose return value was not used, 3. an if statement checking if zero was not zero, and 4. call to platform_get_resource whose return value was not used. Ah, yes, and of course, final return 0. ;) Since omap1_spi100k_remove no longer does anything, it can be safely removed.

2013-02-05spi: Remove erroneous __init, __exit and __exit_p() references in driversGrant Likely1-3/+3
Some of the spi driver module remove hooks were annotated with __exit and referenced with __exit_p(). Presumably these were supposed to be __devinit, __devexit and __devexit_p() since __init/__exit for a probe/remove hook has never been correct. They also got missed during the big __devinit/__devexit purge since they didn't match the pattern. Remove then now to be rid of it. v2: purge __init also Reported-by: Arnd Bergmann <arnd@arndb.de> [Arnd set a patch cleaning up one, and then I found more] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2012-12-07spi: Remove HOTPLUG section attributesGrant Likely1-1/+1
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.

2012-09-22SPI: OMAP: remove unnecessary includes of plat/clock.hPaul Walmsley1-2/+0
Remove unnecessary includes of plat/clock.h from the OMAP SPI controller drivers. These need to be removed to build multi-subarch ARM kernels which include these drivers.

2011-06-06spi: reorganize driversGrant Likely1-0/+637
Sort the SPI makefile and enforce the naming convention spi_*.c for spi drivers. This change also rolls the contents of atmel_spi.h into the .c file since there is only one user of that particular include file. v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be be the predominant pattern for subsystem prefixes. - Clean up filenames in Kconfig and header comment blocks Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
