9b60e2ae51 wifi: mt76: mt7915: firmware restart on devices with a second pcie link 
It seems that the firmware checks the register used for detecting matching

in order to fix an issue that left the second band unusable after restart.

8ad8b8c2dc wifi: mt76: mt7925: replace zero-length array with flexible-array member 
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1],
introduced in C99:

struct foo {
	int stuff;
	struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last, which is beneficial
to cultivate a high-quality code.[2]

This issue was found with the help of Coccinelle.
