Colin Ian King 126c9cb999 pinctrl: rzn1: Make array reg_drive static, makes object smaller
Don't populate the array reg_drive on the stack but instead make it
static. Makes the object code smaller by 32 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  31991	  15696	      0	  47687	   ba47	drivers/pinctrl/pinctrl-rzn1.o

After:
   text	   data	    bss	    dec	    hex	filename
  31863	  15792	      0	  47655	   ba27	drivers/pinctrl/pinctrl-rzn1.o

(gcc version 9.2.1, amd64)

Nishka Dasgupta 2f64dc70ba pinctrl: rzn1: Add of_node_put() before return
Each iteration of for_each_child_of_node puts the previous node, but in
the case of a return from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put before the return in
three places.
Issue found with Coccinelle.

Phil Edworthy 3f3327dbc5 pinctrl: rzn1: Fix of_get_child_count() error check
If we assign the result of of_get_child_count() to an unsigned int,
the code will not detect any errors. Therefore assign it to an int
instead.
