2013-08-05mtd: nand: orion_nand: remove unnecessary platform_set_drvdata()Jingoo Han1-1/+0
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2013-08-05mtd: nand: pxa3xx: Set info->use_dma properlyEzequiel Garcia1-0/+1
Currently, the variable info->use_dma is never set and always zero-valued which means the driver never does DMA transfers. We fix this by simply setting info->use_dma to the module parameter, also named 'use_dma'. Note that the module parameter has the same name, but different semantics. This fixes a regression introduced by the below commit which removed the info->use_dma variable set. commit 4eb2da8994042d68e84e31138788429a102da2ea Author: Lei Wen <leiwen@marvell.com> Date: Mon Feb 28 10:32:13 2011 +0800 mtd: pxa3xx_nand: unify prepare command Before the above commit, the driver had use_dma=1 on all NAND commands except on CMD_STATUS. This behavior is long lost and we are not recovering in this patch, either. This was spotted and verified by human inspection.

Pull removal of GENERIC_GPIO from Grant Likely: "GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it is possible to do so which has been causing confusion and breakage.

2013-04-16Convert selectors of GENERIC_GPIO to GPIOLIBAlexandre Courbot1-1/+1
GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.

Since this driver is dt only and denali_nand_dt_ids is always compiled in, use of of_match_ptr() macro is not necessary.

2013-04-05mtd: denali_dt: Change return value to fix smatch warningSachin Kamat1-1/+1
platform_get_irq() also returns -ENXIO upon failure. Use it instead of hardcoded return type. Fixes the following smatch warning: drivers/mtd/nand/denali_dt.c:93 denali_dt_probe() info: why not propagate 'denali->irq' from platform_get_irq() instead of (-6)?
