perf tests: Do not use sizeof on pointer type
Author: Vaishali Thakkar <vaishali.thakkar@oracle.com> Using sizeof on a malloced pointer type will return the wordsize which can often cause one to allocate a buffer much smaller than it is needed. So, here do not use sizeof on pointer type. Note that this has no effect on runtime because ‘dsos’ is a pointer to a pointer. …

clk: bcm/kona: Do not use sizeof on pointer type
Author: Vaishali Thakkar <vaishali.thakkar@oracle.com> When sizeof is applied to a pointer typed expression, it gives the size of the pointer. So, here do not use sizeof on pointer type. Also, silent checkpatch.pl by using kmalloc_array over kmalloc. Note that this has no effect on runtime because ‘parent_names’ is a pointer to a pointer. Problem found …

drm/msm: Move call to PTR_ERR_OR_ZERO after reassignment
Author: Vaishali Thakkar <vaishali.thakkar@oracle.com> Here, a location is reset to NULL before being passed to PTR_ERR. So, PTR_ERR should be called before its argument is reassigned to NULL. Further to simplify things use PTR_ERR_OR_ZERO instead of PTR_ERR and IS_ERR. Problem found using Coccinelle.
