In the PN532 User Manual (http://www.nxp.com/documents/user_manual/141520.pdf), section 6.2.1, the data checksum (DCS) is defined as: TFI + PD0 + PD1 + ... + PDn + DCS = 0x00. The removed line conveniently had no net affect on the checksum outcome due to the values represented by the preamble and startcode (0x00 and 0xFF). Removing it simply improves readability.

Hi,
This pull request:
In the PN532 User Manual (http://www.nxp.com/documents/user_manual/141520.pdf), section 6.2.1, the data checksum (DCS) is defined as:
TFI + PD0 + PD1 + ... + PDn + DCS = 0x00.The removed lines conveniently had no net effect on the checksum outcome due to the values represented by preamble and startcode (0x00 and 0xFF). Removing it simply improves readability to those following along with the code.
Thanks,
Christopher Bero
