hex2bin converts a hexadecimal string to its binary representation. The original version of hex2bin did not do any error checking. This patch adds error checking and returns the result. Changelog v1: - removed unpack_hex_byte() - changed return code from boolean to int Changelog: - use the new unpack_hex_byte() - add __must_check compiler option (Andy Shevchenko's suggestion) - change function API to return error checking result (based on Tetsuo Handa's initial patch) Signed-off-by: Mimi Zohar <[email protected]> Acked-by: Andy Shevchenko <[email protected]>
