The commit fc3a2fcaa1ba ("mwifiex: use atomic bitops to represent adapter status variables") had a fairly straightforward bug in it. It contained this bit of diff:
- if (!adapter->is_suspended) { + if (test_bit(MWIFIEX_IS_SUSPENDED, &adapter->work_flags)) {
As you can see the patch missed the "!" when converting to the atomic bitops. This meant that the resume hasn't done anything at all since that commit landed and suspend/resume for mwifiex SDIO cards has been totally broken.
After fixing this mwifiex suspend/resume appears to work again, at least with the simple testing I've done.
