[media] si2168: change the i2c gate to be mux-locked The root i2c adapter lock is then no longer held by the i2c mux during accesses behind the i2c gate, and such accesses need to take that lock just like any other ordinary i2c accesses do. So, declare the i2c gate mux-locked, and zap the code that makes the i2c accesses unlocked. But add a mutex so that firmware commands are still serialized.

[media] dvb: Get rid of typedev usage for enums The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

[media] si2168: add ts_mode setting and move to si2168_init Luis Alves submitted a TS mode patch to si2168 earlier, but the patch was rejected due to a small issue. Here is a working version. Also, setting of TS mode is moved from si2168_set_frontend to si2168_init. This patch adds the TS mode as a config option for the si2168 demod: - ts_mode added to config struct. - Possible (interesting) values are * Parallel mode = 0x06 * Serial mode = 0x03 Currently the modules using this demod only use parallel mode.
