Subject: NFC: digital: Fix incorrect use of ERR_PTR and PTR_ERR macros
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=67af1d7a0fb4b5397cb093c0fe98d5b95516c228;p=linux-beck.git

NFC: digital: Fix incorrect use of ERR_PTR and PTR_ERR macros

It's bad to use these macros when not dealing with error code. this
patch changes calls to these macros with correct casts.
