Commit 59714d65dfbc86d5cb93adc5bac57a921cc2fa84

Authored by Andrew Morton
Committed by Linus Torvalds
1 parent 0ccf831cbe
Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

get_task_comm(): return the result 

It was dumb to make get_task_comm() return void.  Change it to return a
pointer to the resulting output for caller convenience.
