media: helene: add I2C device probe function

This patch adds I2C probe function to use dvb_module_probe() with this driver. And also support multiple delivery systems at the same device. Signed-off-by: Katsuhiro Suzuki Signed-off-by: Mauro Carvalho Chehab

media: dvb: convert tuner_info frequencies to Hz

2018-08-02T20:14:50Z

Right now, satellite tuner drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal tuners capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid tuners. So, convert everything to specify tuner frequencies in Hz. Plese notice that a similar patch is also needed for frontends. Tested-by: Katsuhiro Suzuki Acked-by: Michael Büsch Signed-off-by: Mauro Carvalho Chehab

A typical code fragment was copied across many dvb-frontend drivers and causes large stack frames when built with with CONFIG_KASAN on gcc-5/6/7: drivers/media/dvb-frontends/cxd2841er.c:3225:1: error: the frame size of 3992 bytes is larger than 3072 bytes [-Werror=frame-larger-than=] drivers/media/dvb-frontends/cxd2841er.c:3404:1: error: the frame size of 3136 bytes is larger than 3072 bytes [-Werror=frame-larger-than=] drivers/media/dvb-frontends/stv0367.c:3143:1: error: the frame size of 4016 bytes is larger than 3072 bytes [-Werror=frame-larger-than=] drivers/media/dvb-frontends/stv090x.c:3430:1: error: the frame size of 5312 bytes is larger than 3072 bytes [-Werror=frame-larger-than=] drivers/media/dvb-frontends/stv090x.c:4248:1: error: the frame size of 4872 bytes is larger than 3072 bytes [-Werror=frame-larger-than=] gcc-8 now solves this by consolidating the stack slots for the argument variables, but on older compilers we can get the same behavior by taking the pointer of a local variable rather than the inline function argument.

lib/vsprintf.c: remove %Z support

2017-02-28T02:43:47Z

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers. In case anyone didn't notice lib/vsprintf.o is about half of SLUB which is in my opinion is quite an achievement. Hopefully this patch inspires someone else to trim vsprintf.c more.
