common: hash: zero end the string instead of the pointer
if algo->digest_size is zero nothing is set in the str_output buffer. An attempt is made to zero end the buffer, but the pointer to the buffer is set to zero instead. I am unaware if it causes any actual problems, but solves the following warning: common/hash.c:217:13: warning: expression which evaluates to zero treated as a null pointer constant of type 'char *' [-Wnon-literal-null-conversion] str_ptr = '\0'; ^~~~ cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
