Subject: NFC: st21nfcb: remove error output
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc6b8275924b8af3d10ac35df0579d94fa169680;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

NFC: st21nfcb: remove error output

In case we are not able to read out the NDLC/NCI header, we do not
consider this as an issue and we will give a later chance.
The NDLC layer will handle errors thanks to its internal timers.
