2011-05-20[media] cx24116: add config option to split firmware downloadAntti Palosaari2-3/+17
It is very rare I2C adapter hardware which can provide 32kB I2C write as one write. Add .i2c_wr_max option to set desired max packet size. Split transaction to smaller pieces according to that option.

2011-05-20[media] STV0299 incorrect standby setting issues register 02 (MCR)Malcolm Priestley1-2/+8
Issues with Register 02 causing spurious channel locking from standby. Should have always bits 4 & 5 written to 1. Lower nibble not used in any current driver. Usage if necessary can be applied through initab to mcr_reg. stv0299 not out of standby before writing inittab.

2011-05-20[media] Media, DVB, Siano, smsusb: Avoid static analysis report about 'use ↵Jesper Juhl1-2/+1
after free' In drivers/media/dvb/siano/smsusb.c we have this code: ... kfree(dev); sms_info("device %p destroyed", dev); ... at least one static analysis tool (Coverity Prevent) complains about this as a use-after-free bug. While it's true that we do use the pointer variable after freeing it, the only use is to print the value of the pointer, so there's not actually any problem here. But still, silencing the complaint is trivial by just moving the kfree() call below the sms_info(), so why not just do it?. It doesn't change the workings of the code in any way, but it makes the tool shut up. The patch below also removes a rather pointless blank line.
