Subject: lib: Improve _parse_integer_fixup_radix base 16 detection
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=0486497e2b5f4d36fa968a1a60fea358cbf70b65;p=u-boot.git

lib: Improve _parse_integer_fixup_radix base 16 detection

Base autodetection is failing for this case:
if test 257 -gt 3ae; then echo first; else echo second; fi

It is because base for 3ae is recognized by _parse_integer_fixup_radix() as
10. The code detects the first char which is not between 'a'/'A' or 'f'/'F'
to change base from dec to hex.
