Add 1 to the size passed to kzalloc after replacing one-element array. There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct phm_ppt_v1_mm_clock_voltage_dependency_table, instead of a one-element array, and use the struct_size() helper to calculate the size for the allocation.
