[PATCH] Input: fix odd_ptr_err.cocci warnings

[kernel test robot]

From: kernel test robot <lkp at intel.com>

drivers/input/misc/isa1200.c:327:5-11: inconsistent IS_ERR and PTR_ERR on line 328.
drivers/input/misc/isa1200.c:332:5-11: inconsistent IS_ERR and PTR_ERR on line 333.

 PTR_ERR should access the value just tested by IS_ERR

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