After a recent series to use FIELD_PREP and FIELD_MODIFY in
tidss_dispc.c, there are many errors when bitfield.h is not implicitly
included, such as when building allmodconfig for ARCH=hexagon:
drivers/gpu/drm/tidss/tidss_dispc.c:1116:2: error: call to undeclared function 'FIELD_MODIFY'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
1116 | VP_REG_FLD_MOD(dispc, hw_videoport, DISPC_VP_CONTROL, v,

drivers/gpu/drm/tidss/tidss_dispc.c:631:3: note: expanded from macro 'VP_REG_FLD_MOD'
631 | FIELD_MODIFY((mask), &_reg, (val)); \

drivers/gpu/drm/tidss/tidss_dispc.c:1140:2: error: call to undeclared function 'FIELD_MODIFY'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

drivers/gpu/drm/tidss/tidss_dispc.c:1203:10: error: call to undeclared function 'FIELD_PREP'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
1203 | FIELD_PREP(DISPC_VP_TIMING_H_SYNC_PULSE_MASK, hsw - 1) |

...
Explicitly include bitfield.h to resolve the errors.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
