Subject: consolemap: Fix a memory leaking bug in drivers/tty/vt/consolemap.c
|
||||
|
||||
In function con_insert_unipair(), when allocation for p2 and p1[n]
|
||||
fails, ENOMEM is returned, but previously allocated p1 is not freed,
|
||||
remains as leaking memory. Thus we should free p1 as well when this
|
||||
allocation fails.
