X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0d88002e2729e93d93631743d57e1f36763ce136;p=deliverable%2Flinux.git

usb/host/fotg210: change kmalloc by kmalloc_array

This patch replaces:

kmalloc(DBG_SCHED_LIMIT * sizeof(*seen), GFP_ATOMIC)

by:

kmalloc_array(DBG_SCHED_LIMIT, sizeof(*seen), GFP_ATOMIC)

as kmalloc_array() should be used for allocating arrays.
