Scott Shawcroft d2860b58b0 Check background pending before sleep ... There is a race between when we run background tasks and when we sleep. If an interrupt happens between the two, then we may delay executing the background task. On some ports we checked this for TinyUSB already. On iMX RT, we didn't which caused USB issues. This PR makes it more generic for all background tasks including USB. Fixes #5086 and maybe others.		2021-08-19 12:18:13 -07:00
