 PTR_ERR should normally access the value just tested by IS_ERR

Generated by: scripts/coccinelle/tests/odd_ptr_err.cocci

Fixes: 460e9d2590fe ("regulator: lp8788-ldo: Pass descriptor instead of GPIO number")
Signed-off-by: Fengguang Wu <>
Signed-off-by: Julia Lawall <>

Semantic patch information:
 There can be false positives in the patch case, where it is the call to
 IS_ERR that is wrong.
