[flashrom] [PATCH] Workaround missing %hhx support in MinGW sscanf

[Idwer Vollering]

2012/2/16 Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006 at gmx.net>:
> MinGW uses standard Windows C libraries and those apparently don't
> support %hhx for sscanf into a uint8_t. SCNx8 isn't available either.
