[PATCH v2] ASoC: stm32: sai: Fix invalid use of sizeof in stm32_sai_add_mclk_provider()

From: Wen Yang
Date: Wed Nov 28 2018 - 20:44:49 EST

sizeof(mclk) is 4 or 8 as it is the size of a pointer,
but we want to reserve space for the pointed data.
This issue was detected by using the Coccinelle software.

v2: use subject lines matching the style for the subsystem.
