2019-06-17iio: imx7d_adc: Remove unneeded error messageFabio Estevam1-5/+2
In case of ioremap failure, the core code will take care of printing the error message, so there is no need for having a local error message in the driver. Signed-off-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2019-06-17iio:core: Fix bug in length of event info_mask and catch unhandled bits set ↵Young Xiao1-0/+2
in masks. The incorrect limit for the for_each_set_bit loop was noticed whilst fixing this other case. Note that as we only have 3 possible entries a the moment and the value was set to 4, the bug would not have any effect currently. It will bite fairly soon though, so best fix it now. See commit ef4b4856593f ("iio:core: Fix bug in length of event info_mask and catch unhandled bits set in masks.") for details.

2019-06-17staging: iio: ad2s1210: Remove platform data NULL check in probeAlexandru Ardelean1-3/+0
The driver only needs to access GPIOs via GPIOLIB. And SPI can be configured via device-tree or ACPI. The platform data is a remnant from another time, and should not cause the driver to error out during probing if it is NULL. Also, it's not used.

The device dependent options which are going to be different for devices which will be supported in the future by this driver, were moved in chip info for a more generic driver. This patch allows supporting more devices by the driver. Also, it is an intermediate step of adding support for ad7616 in software mode.

2019-05-23staging: unisys: visornic: Replace GFP_ATOMIC with GFP_KERNELHariprasad Kelam1-2/+2
As per below information GFP_KERNEL FLAG This is a normal allocation and might block. This is the flag to use in process context code when it is safe to sleep. GFP_ATOMIC FLAG The allocation is high-priority and does not sleep. This is the flag to use in interrupt handlers, bottom halves and other situations where you cannot sleep And we can take advantage of GFP_KERNEL , as when system is in low memory chances of getting success is high compared to GFP_ATOMIC.
