[media] stv0367: Don't use dynamic static allocation Dynamic static allocation is evil, as Kernel stack is too low, and compilation complains about it on some archs: drivers/media/dvb-frontends/stv0367.c:791:1: warning: 'stv0367_writeregs.constprop.4' uses dynamic stack allocation [enabled by default] Instead, let's enforce a limit for the buffer. Considering that I2C transfers are generally limited, and that devices used on USB has a max data length of 64 bytes for the control URBs. So, it seem safe to use 64 bytes as the hard limit for all those devices. On most cases, the limit is a way lower than that, but this limit is small enough to not affect the Kernel stack, and it is a no brain limit, as using smaller ones would require to either carefully each driver or to take a look on each datasheet.

[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.

[media] tuners: remove dvb_frontend_parameters from set_params() This is a big patch, yet trivial: now that all tuners use the DVBv5 way to pass parameters (e. g. via fe->dtv_property_cache), the extra parameter can be removed from set_params() call. After this change, very few DVBv3 specific stuff are left at the tuners. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

[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] 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] tuners: remove dvb_frontend_parameters from set_params() This is a big patch, yet trivial: now that all tuners use the DVBv5 way to pass parameters (e. g. via fe->dtv_property_cache), the extra parameter can be removed from set_params() call. After this change, very few DVBv3 specific stuff are left at the tuners. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
