From 7310dd3fbaa5a23f2b4a1c17ece2a0c7434a1d98 Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Sat, 6 Jun 2020 09:53:06 -0700 Subject: Bluetooth: hci_qca: Simplify determination of serial clock on/off state from votes The serial clocks should be on when there is a vote for at least one of the clocks (RX or TX), and off when there is no 'on' vote. The current logic to determine the combined state is a bit redundant in the code paths for different types of votes, use a single statement in the common path instead.
