Subject: [PATCH] mtd: atmel-quadspi: fix odd_ptr_err.cocci warnings

drivers/mtd/spi-nor/atmel-quadspi.c:758:5-11: inconsistent IS_ERR and PTR_ERR on line 760.

 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.

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

Please take the patch only if it's a positive warning. Thanks!
