media: ccs: Avoid deadlock in ccs_init_state()

2026-03-26T12:14:07+00:00

The sub-device state lock has been already acquired when ccs_init_state()
is called. Do not try to acquire it again.

kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove  from  and update all users/callers of
hex.h interfaces to directly #include  as part of the process
of putting kernel.h on a diet.

Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.

This change has been build-tested with allmodconfig on most ARCHes.  Also,
all users/callers of  in the entire source tree have been
updated if needed (if not already #included).
