Subject: [PATCH] drivers/pcmcia: omap1: Fix error in automated timer
 conversion

One part of automated timer conversion tools did not take into account
void * variables when searching out prior direct timer callback usage,
which resulted in an attempt to dereference the timer field without a
proper type.
