-Subject: [PATCH 110/222] mailbox/bcm2835: Fix mailbox full detection.
-
-With the VC reader blocked and the ARM writing, MAIL0_STA reads empty
-permanently while MAIL1_STA goes from empty (0x40000000) to non-empty
-(0x00000001-0x00000007) to full (0x80000008).
-
-This bug ended up having no effect on us, because all of our
-transactions in the client driver were synchronous and under a mutex.
