The address of a data structure member was determined before
a corresponding null pointer check in the implementation of
the function “au1100fb_setmode”.

Thus avoid the risk for undefined behaviour by moving the assignment
for the variable “info” behind the null pointer check.

This issue was detected by using the Coccinelle software.
