There is an asymmetry in ttusb_dec_init_usb()-ttusb_init_rc() and ttusb_dec_exit_usb()-ttusb_dec_exit_rc() in terms of resources allocated-deallocated. irq_urb and irq_buffer are allocated in ttusb_dec_init_usb(), while they are deallocated in ttusb_dec_exit_rc(). As a result there is a leak of them in ttusb_dec_probe(). The patch fixes the asymmetry and a leak on a failure path in ttusb_dec_init_usb(). By the way, it - removes usage of -1 as a custom error code, - replaces GFP_ATOMIC by GFP_KERNEL in usb_alloc_coherent() in ttusb_dec_init_usb() as soon as all other memory allocation done with GFP_KERNEL; - refactors ttusb_dec_boot_dsp() in an equivalent way except for returning 0 instead of 1 if ttusb_dec_boot_dsp() succeed in (!mode) branch.

Changeset 9e8da9e8 added a parameter to specify the frequency divisor, used by the driver. However, not all places are passing this parameter. So, preserve the previous default, to avoid breaking the existing drivers. Signed-off-by: -

[media] media: dvb-frontends: ts2020: Added in a option for frequency divider value for s600 devices When the tuner part of the ds3000 driver was split to share code with the m88rs2000 driver, the ts2020 driver used the frequency divider value from the m88rs2000 driver. However the ds3000 driver requires a different value, and this resulted in some frequecies being invisible to the tuner. This patch adds back in the value needed for the ds3000 driver and configured as an option in the dw2102 frontend driver. It may also apply to su3000 devices, which use the same ds3000 driver, but for now it is only applied to the s660 device. Signed-off-by:

Reading firmware status register to detect whether firmware is running or not didn't work 100% reliably. That register was likely set by firmware itself which means it could not contain reasonable values until firmware is up and running. Usually it just worked as some garbage value was returned accidentally but it appears that in some cases returned garbage value was 0x00 which was considered "firmware is up and running" by the driver and firmware loading was skipped leaving device to non-working state. Fix problem by removing unreliable check and let the driver keep count whether firmware is loaded or not. Signed-off-by:

Most DMA engines have limitations regarding the number of DMA segments (sg-buffers) that they can handle. Videobuffers can easily spread through hundreds of pages. In the previous aproach, the pages were allocated individually, this could led to the creation houndreds of dma segments (sg-buffers) that could not be handled by some DMA engines. This patch tries to minimize the number of DMA segments by using alloc_pages. In the worst case it will behave as before, but most of the times it will reduce the number of dma segments Acked-by:
