Subject: [PATCH] BT: Once AT command is retrieved, return from method.
|
|
|
|
- Observed SIGSEV issue in Defensics, when received
|
|
buf is more than BTA_HF_CLIENT_AT_PARSER_MAX_LEN.
|
|
|
|
- Commented recover cut data, after AT command is
|
|
retrieved because leftover data/buf is more than
|
|
BTA_HF_CLIENT_AT_PARSER_MAX_LEN and leading to
|
|
offset corruption.
