Next: linux-next: Tree for May 25 (kernel/power, SUSPEND=n)
From: Will Drewry on 25 May 2010 11:50 name_to_dev_t takes a char * argument which it never modifies. This change converts it to a const char *. (This is useful with the second patch in the series which exports the symbol. External consumers of the function will now be able to pass in a const char * without duping or casting away const-ness.)
