sdhci: 'scratch' may be used uninitialized
The variable 'scratch' is always initialized before it's used. The conditional which is responsible for initialization of 'scratch' will always evaluate 'true' when the first loop iteration occurs, and thus, it's properly initialized. GCC doesn't see this, of course, so using the uninitialized_var() macro seems to work for silencing this case.
