* include/linux/delay.h: replace kernel.h with the necessary inclusionsAndy Shevchenko2021-11-091-0/+1
| | | | | | | | | | | | | | | | | When kernel.h is used in the headers it adds a lot into dependency hell, especially when there are circular dependencies are involved. Replace kernel.h inclusion with the list of what is really being used.

* media: dvb: remove redundant assignment to variable bwColin Ian King2020-05-121-1/+1
| | | | | | | | | | | | The variable bw is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

* media: dvb: represent min/max/step/tolerance freqs in HzMauro Carvalho Chehab2018-08-021-3/+3
| | | | | | | | | | | | | | | | Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends 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 frontends. So, convert everything to specify frontend frequencies in Hz.
