Subject: dlm: Use kcalloc() in dlm_scan_waiters()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fbb1008151cabb83aeadf91ae363196def070eba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dlm: Use kcalloc() in dlm_scan_waiters()

A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
