Subject: PCI: mvebu: Use devm_kcalloc() to allocate an array
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=19fdb80091a8f3c09b7293bb299f6eb46c6ae070;p=linux-beck.git

PCI: mvebu: Use devm_kcalloc() to allocate an array

Rather than using devm_kzalloc() and multiplying the element and number,
use the provided devm_kcalloc() helper for this.
