Subject: ionic: use kcalloc for new arrays
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ee205626afa3960fb6353fd6c7a51522c5ce7686;p=linux.git

ionic: use kcalloc for new arrays

Use kcalloc for allocating arrays of structures.

Following along after
commit e71642009cbdA ("ionic_lif: Use devm_kcalloc() in ionic_qcq_alloc()")
there are a couple more array allocations that can be converted
to using devm_kcalloc().
