[PATCH v2 0/2] MR8762: win32u: Remove a log message in get_shared_window.

[Tim Clem (＠tclem)]

This message is *very* noisy and totally dominates +win (e.g. it printed 1.5 million times in a relatively short log of a Steam session). Is it useful? If so, perhaps we could log only around the error conditions?

[PATCH v2 1/2] win32u: Fix an uninitialized variable warning.

[Tim Clem]

From: Tim Clem

Effectively a false positive, since we only use window_shm if
get_shared_window succeeds, but the compiler doesn't know that.

Oh strange, I wouldn't have expected the log change to expose that. Added another commit for that in v2.
