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:90 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 85 vivid-rds-gen.c:92 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 86 vivid-rds-gen.c:93 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 87 Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>	2016-04-20 15:47:33 -03:00

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.
