media: tda10071: fix unsigned sign extension overflow

2020-03-12T08:46:45Z

The shifting of buf[3] by 24 bits to the left will be promoted to a 32 bit signed int and then sign-extended to an unsigned long. In the unlikely event that the the top bit of buf[3] is set then all then all the upper bits end up as also being set because of the sign-extension and this affect the ev->post_bit_error sum. Fix this by using the temporary u32 variable bit_error to avoid the sign-extension promotion. This also removes the need to do the computation twice.

media: m88ds3103: Add support for ds3103b demod

2020-03-12T08:25:21Z

The ds3103b demodulator identifies as an m88rs600, but requires different clock settings and firmware, along with differences in register settings. Changes were reverse engineered using an instrumented downstream GPLv2 driver to compare i2c traffic and clocking. The mclk functions are from the downstream GPLv2 driver.

media: drxj: remove redundant assignments to variable rc

2020-02-24T15:26:14Z

The variable rc is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed. Addresses-Coverity: ("Unused value") Signed-off-by: Colin Ian King Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab
