Arnd Bergmann 41e3308528 media: vivid: print time in y2038-safe way 
time_to_tm() takes a time_t value that overflows in 2038 on 32-bit
systems. time64_to_tm() doesn't have this problem, so let's use that in
combination with ktime_get_real_seconds() to read a 64-bit time
value.

Hans Verkuil 86b2749ba7 [media] vivid: fix smatch errors 
The smatch utility got really confused about the grp % 22 code. Rewrote
it so it now understands that there really isn't a buffer overwrite.

vivid-rds-gen.c:82 vivid_rds_generate() error: buffer overflow 'rds->psname' 9 <= 43
vivid-rds-gen.c:83 vivid_rds_generate() error: buffer overflow 'rds->psname' 9 <= 42
vivid-rds-gen.c:89 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 84

vivid-rds-gen.c:93 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 87

Hans Verkuil 55d58e9898 [media] vivid: add support for radio receivers and transmitters 
This adds radio receiver and transmitter support. Part of that is common
to both and so is placed in the radio-common source.

These drivers also support RDS. In order to generate valid RDS data a
simple RDS generator is implemented in rds-gen.
