6.6-stable review patch. If anyone has any objections, please let me know.

From: Dan Carpenter dan.carpenter@linaro.org
commit f37e76abd614b68987abc8e5c22d986013349771 upstream.
The m.u.component_create.pid field is for debugging and in the mainline kernel it's not used anything. However, it still needs to be set to something to prevent disclosing uninitialized stack data. Set it to zero.
