If anyone has any objections, please let me know. ------------------ From: Dylan Reid commit c42c8922c46d33ed769e99618bdfba06866a0c72 upstream. Sync regcache when entering STANDBY from OFF. ON isn't entered with OFF as the current state, so the registers were not being re-synced after suspend/resume. The 98088 and 98095 already call regcache_sync from STANDBY.
