* spi: Drop owner assignment from spi_driversAndrew F. Davis2015-10-27
| | | | | | | | | An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
* net: wireless: wl1251: Remove unnecessary free_irqHimangi Saraogi2014-08-25
| | | | | | | | This patch does away with free_irq in the remove function as the irq is allocated with a devm_request_irq. Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* drivers/net/wireless/ti/wl*/spi.c: Simplify CRC computationGeorge Spelvin2014-05-16
| | | | | | | | | | | | | | | | These devices require commands stored in buffers in an odd order, different from that in which the CRC is computed. Rather than make two copies of the commands in two different orders, form the commands in logical (CRC) order, append the CRC, then byte-swap in place to the desired order. The old code worked fine, I'm just scratching an "ugh, that's ugly" itch. Signed-off-by: George Spelvin <linux@horizon.com> Reviewed-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: John W.

* lib/crc7: Shift crc7() output left 1 bitGeorge Spelvin2014-05-16
| | | | | | | | | | | | | | This eliminates a 1-bit left shift in every single caller, and makes the inner loop of the CRC computation more efficient. Renamed crc7 to crc7_be (big-endian) since the interface changed. Also purged #include <linux/crc7.h> from files that don't use it at all.

* wireless: wl1251: use dev_get_platdata()Jingoo Han2013-09-26
| | | | | | | | | Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* wl1251: fix oops on early interruptGrazvydas Ignotas2012-05-25
| | | | | | | | | | | | | | | This driver disables interrupt just after requesting it and enables it later, after interface is up. However currently there is a time window between request_irq() and disable_irq() where if interrupt arrives, the driver oopses because it's not yet ready to process it. This can be reproduced by inserting the module, associating and removing the module multiple times. Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().
