Subject: NFC: Use NFC_MAX_GT_LEN to check len in nci_set_local_general_bytes
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=460d8f970e44c2d8fc24ab622ff433295a6cedd8;p=openwrt%2Fstaging%2Fblogic.git

NFC: Use NFC_MAX_GT_LEN to check len in nci_set_local_general_bytes

local_gb is of size NFC_MAX_GT_LEN and len is used as index for it.
Check len against this instead of NCI_MAX_PARAM_LEN before accessing
local_gb.
