2017-12-15media: dvb-frontends: fix i2c access helpers for KASANArnd Bergmann
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.

2017-02-27lib/vsprintf.c: remove %Z supportAlexey Dobriyan
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.

2016-11-18[media] dvb_frontend: tuner_ops.release returns voidMax Kellermann
It is not clear what this return value means. All implemenations return 0, and the one caller ignores the value. Let's remove this useless return value completely. Signed-off-by: Max Kellermann <max.kellermann@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-19[media] dvb-frontends: constify dvb_tuner_ops structuresJulia Lawall
These structures are only used to copy into other structures, so declare them as const.
