Subject: [PATCH 4.2 003/134] nfc: st-nci: Fix non accurate comment for st_nci_i2c_read

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe Ricard <christophe.ricard@...il.com>

commit e7723b33077b04648213f043bc22654c54e375e4 upstream.

Due to a copy and paste error st_nci_i2c_read still contains
st21nfca header comment.
