6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gergo Koteles soyer@irl.hu
commit 315deab289924c83ab1ded50022e8db95d6e428b upstream.
Calling component_add starts loading the firmware, the callback function writes the program to the amplifiers. If the module resets the amplifiers after component_add, it happens that one of the amplifiers does not work because the reset and program writing are interleaving.
Call tas2781_reset before component_add to ensure reliable initialization.
