Hello
I have a 8335-GCA POWER8 which got a kernel crash during boot:
[ 11.754238] Kernel attempted to read user page (0) - exploit attempt? (uid:

[ 11.754437] BUG: Kernel NULL pointer dereference on read at 0x

pci_driver name is const char pointer, so the cast it not necessary.

nd I didnt found an easy way to

The two last patch are example of convertion of two drivers.
Thoses patchs give an example of the reduction of code won by using xxxbits32.
