[media] dw2102: don't do DMA on stack
On Kernel 4.9, WARNINGs about doing DMA on stack are hit at the dw2102 driver: one in su3000_power_ctrl() and the other in tt_s2_4600_frontend_attach(). Both were due to the use of buffers on the stack as parameters to dvb_usb_generic_rw() and the resulting attempt to do DMA with them. The device was non-functional as a result. So, switch this driver over to use a buffer within the device state structure, as has been done with other DVB-USB drivers. Tested with TechnoTrend TT-connect S2-4600. [mchehab@osg.samsung.com: fixed a warning at su3000_i2c_transfer() that state var were dereferenced before check 'd'] Signed-off-by: Jonathan McDowell <noodles@earth.li> Cc: <stable@vger.kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
