[PATCH v4 0/3] Fix pinctrl-single pcs_pin_dbg_show()

[Hanna Hawa <hhhawa@xxxxxxxxxx>]

These patches fix the pcs_pin_dbg_show() function for the scenario where
a single register controls multiple pins (i.e. bits_per_mux is not zero)
Additionally, the common formula is moved to a separate function to
allow reuse.

Changes since v3:
-----------------
- define and set variable 'mux_bytes' in one line
- update commit message

Changes since v2:
-----------------
- move read() register to be outside of if condition (as it common
  read()).
- Remove extra parentheses
- replace offset variable by direct return statements

Changes since v1:
-----------------
- remove unused variable in In function 'pcs_allocate_pin_table'
  (Reported-by: kernel test robot <lkp@xxxxxxxxx>)

Hanna Hawa (3):
  pinctrl: pinctrl-single: remove unused variable
  pinctrl: pinctrl-single: remove unused parameter
  pinctrl: pinctrl-single: fix pcs_pin_dbg_show() when bits_per_mux is
    not zero
