stlink_chipid_get_params() used to segfault on memcmp() when struct stlink_chipid_params *params was NULL. This could happen if either: - there were no chip config files (*.chip), or - process_chipfile() failed to parse chip_id from the chip config files. The latter case is caused by the usage of atoi() to parse the chip id. Since the chip id is stored in hex, atoi() returns 0; such id cannot be matched to any actual chip. The segfault occurs on commit a52e1bc, in file src/stlink-lib/chipid.c:957 (https://github.com/stlink-org/stlink/blob/a52e1bc5489e23f3c1071c6912820efacaa3b22c/src/stlink-lib/chipid.c#L957). Check if params is NULL, in such case, set it to p2, which should not be NULL as long as struct stlink_chipid_params devices[] exists. May fix (workaround) #1163.
