Subject: dlm: Use kmalloc_array() in make_member_array()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=790854becc1921d0cf46180ee55beb4a1787e680;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dlm: Use kmalloc_array() in make_member_array()

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

  This issue was detected by using the Coccinelle software.

* Replace the specification of a data type by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.
