Kernel for Galaxy S24, rebased on CLO sources (WIP)
dba9e34674
The drm_atomic_get_new_private_obj_state() function returns NULL
on error path, drm_atomic_get_old_private_obj_state() function
returns NULL on error path, too, they does not return error pointers.
By the way, vc4_hvs_get_new/old_global_state() should return
ERR_PTR(-EINVAL), otherwise there will be null-ptr-defer issue,
such as follows:
In function vc4_atomic_commit_tail():
|-- old_hvs_state = vc4_hvs_get_old_global_state(state); <-- return NULL
|-- if (WARN_ON(IS_ERR(old_hvs_state))) <-- no return
|-- unsigned long state_rate = max(old_hvs_state->core_clock_rate,
new_hvs_state->core_clock_rate); <-- null-ptr-defer

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 Restructured Text 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.
