Provide a wrapper to prevent possible ERR_PTR dereference by
clk_get_rate().
The return value of clk_get_sys() was immediately used in
clk_get_rate(). The first one may return ERR_PTR and the latter only

of_clk_get_from_provider() returns ERR_PTR on failure. The
dra7-atl-clock driver was not checking its return value and immediately
used it in __clk_get_hw(). __clk_get_hw() dereferences supplied clock,
if it is not NULL, so in that case it would dereference an ERR_PTR.

Hi,
clk_get_sys() may return ERR_PTR but the drivers immediately
dereferenced the return value. This could lead to oops.
I tried only to fix possible ERR_PTR dereference and to not change
the logic. This is why some of the patches look quite complex.
For example in clk-7xx driver proceeds to nex

Added a new function sysfs_link_group_to_kobj() that adds a symlink
from attribute or group to a kobject. Exported kernfs_remove_by_name_ns

Moved PPI attributes to the character device directory. This aligns with
the sysfs guidelines and makes them race free because they are created
atomically with the character device as part of device_register().The
character device and the sysfs attributes appear at the same time to the
user space.
Changes since v4:
* Removed dangling export of kernfs_remove_by_name_ns() from the sysfs
patch.
Changes since v3:
* Use sysfs_remove_link()
Changes since v2:
* Fixed to_tpm_chip() macro.

Function pick_next_earliest_dl_task is used to pick earliest and pushable
dl task from overloaded cpus in pull algorithm, however, it traverses
runqueue rbtree instead of pushable task rbtree which is also ordered by
tasks' deadlines. This will result in getting no candidates from overloaded
cpus i
pull_dl_task can drop (and re-acquire) rq->lock, this means a stop task
can slip in, in which case we need to reschedule. This patch add the
reschedule when the scenario occurs.

Resetting dl_throttled flag in rt_mutex_setprio (for a task that is going
