This warning has appeared after the AT91_ADC driver compilation has been enabled via the COMPILE_TEST symbol dependency. The warning is caused by the 'of_match_ptr()' helper which returns NULL if OF is undefined. This driver should build only for device-tree context, so a dependency on the OF Kconfig symbol has been added. Also, the usage of of_match_ptr() helper has been removed since it shouldn't ever return NULL (because the driver should not be built for the non-OF context).
