include/linux/delay.h: replace kernel.h with the necessary inclusions

2021-11-09T18:02:49+00:00

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: rtl2832_sdr: clean the freed pointer and counter

2021-10-08T11:54:16+00:00

After freed the dev->urb_list, we should set it to NULL as well as set
counter to zero.

media: dvb-frontends: mn88443x: Handle errors of clk_prepare_enable()

2021-10-08T11:53:30+00:00

mn88443x_cmn_power_on() did not handle possible errors of
clk_prepare_enable() and always finished successfully so that its caller
mn88443x_probe() did not care about failed preparing/enabling of clocks
as well.

Add missed error handling in both mn88443x_cmn_power_on() and
mn88443x_probe(). This required to change the return value of the former
from "void" to "int".

media: mb86a20s: make arrays static const

2021-10-08T11:43:54+00:00

Don't populate the read-only arrays on the stack but instead them
static const. Also makes the object code smaller by 154 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  42949	  22424	      0	  65373	   ff5d	media/dvb-frontends/mb86a20s.o

After:
   text	   data	    bss	    dec	    hex	filename
  42731	  22488	      0	  65219	   fec3	media/dvb-frontends/mb86a20s.o
