2013-03-15Staging: dwc2: remove a kfree(NULL)Dan Carpenter
dwc2_hcd_release() calls dwc2_hcd_free() which frees ->core_params and sets it to NULL. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-15staging: sep: fix possible memory leak in sep_prepare_input_dma_table()Wei Yongjun
'lli_array_ptr' etc. are malloced in sep_prepare_input_dma_table() and should be freed before leaving from the error handling case, otherwise it will cause memory leak. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-15staging: omap-thermal: add documentation for omap_bandgap_validateEduardo Valentin
Document the helper to validate a struct omap_bandgap and a sensor id. Signed-off-by: Eduardo Valentin <eduardo.valentin@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-15staging: omap-thermal: remove TODO entry for exposed APIsEduardo Valentin
Not all APIs exposed today are used. However all unused APIs will be required once the thermal layer allows IRQ based policies. Signed-off-by: Eduardo Valentin <eduardo.valentin@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-15staging: omap-thermal: remove TODO entry suggesting regmap usageEduardo Valentin
It is hard to use regmap because benefit of using regmap cache may not be applicable as there is a specific sequence to restore the bandgap context. Signed-off-by: Eduardo Valentin <eduardo.valentin@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-15staging: omap-thermal: switch mutex to spinlock inside omap-bandgapEduardo Valentin
Because there is a need to lock inside IRQ handler, this patch changes the locking mechanism inside the omap-bandgap.[c,h] to spinlocks. Now this lock is used to protect omap_bandgap struct during APIs exposed (possibly used in sysfs handling functions) and inside the ALERT IRQ handler. Because there are registers shared among the sensors, this lock is global, not per sensor.

2013-03-15staging: omap-thermal: change Kconfig dependency methodEduardo Valentin
Now arch code has to specify CONFIG_ARCH_HAS_BANDGAP. So, this driver will be selectable only if the platform reports itself as having a bandgap device. Any OMAP variant or any other OMAP version needs to select ARCH_HAS_BANDGAP so that the driver will be applicable. A part from that it is required to device the data structures that maps the registers and their bitfields. The DT compatible list must also be updated.

2013-03-15staging: omap-thermal: refactor APIs handling threshold valuesEduardo Valentin
This patch improves the code that handles threshold values by creating single functions that are usable for tcold and thot. This way we won't have duplicated functionality just because it is handling different bitfields. Now the added functions are reused in several places where it is needed to update any threshold. This patch also removes macros that are used only inside the _validate helper function. In this patch there is also an addition of an extra function section for Exposed APIs, used outside the omap-bandgap.c, but inside the omap-thermal driver.
