[PATCH v2 11/24] selftests/resctrl: Remove start_buf local variable from buffer alloc func

From: Ilpo Järvinen
Date: Tue Apr 18 2023 - 07:46:55 EST


alloc_buffer() has local start_ptr variable which is unnecessary.

Assign the pointer of the allocated buffer directly to startptr that is
a global variable in fill_buf to simplify the code in alloc_buffer().
