We manually init wakeup info, but we don't detach it on device removal. This means that if we (for example) rmmod + modprobe the driver, the device framework might return -EEXIST the second time, and we'll complain in the logs: [ 839.311881] mwifiex_pcie 0000:01:00.0: fail to init wakeup for mwifiex AFAICT, there's no other negative effect. But we can fix this by disabling wakeup on remove, similar to what a few other drivers do (e.g., the power supply framework). This code (and bug) has existed on SDIO for a while, but it got moved around and enabled for PCIe with commit 853402a00823 ("mwifiex: Enable WoWLAN for both sdio and pcie").
