[PATCH 1/2] drivers: acpi: use %pe for better readability of errors while printing

[Onkarnarth]

From: Onkarnath <onkarnath.1@samsung.com>

As %pe is already introduced, its better to use it inplace of (%ld) for
printing errors in logs. It would enhance redability of logs.

[PATCH 2/2] kernel: sched: print errors with %pe for better readability of logs

[Onkarnarth]

From: Onkarnath <onkarnath.1@samsung.com>

instead of printing errros as a number(%ld), it's better to print in string
format for better readability of logs.

I quick ripgrep tells me this is the only culprit in sched, so:

s/its/it's/
s/inplace/in place/
s/redability/readability/

In the subject line, run "git log --oneline drivers/acpi" and pick
something that fits with the history instead of just encoding the file
path.  Same for the sched patch.
