tlv: add TLV_GET() and TLV_GET_MINLEN()
Rationale: so far we use code like if (TLVP_PRESENT(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS)) { val = TLVP_VAL(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); len = TLVP_LEN(&tp, VERY_L0NG_ENUM_VALUE_NAME_TH4T_NEVER_EMDS); } This is a) very long and b) prone to picking the wrong name one of the three times, which would use the wrong length or val without necessarily being noticed. A safer and shorter, more readable pattern is: struct tlv_p_entry *e = TVLP_GET(&tp, VERY_LONG_ENUM_VALUE_NAME_THAT_NEVER_ENDS); if (!e) return -ENOENT; hexdump(e->val, e->len); Change-Id: I445de17fc2daa3ab051f5708dd0cc185b23dc048
