-Subject: [PATCH 257/304] clk: bcm2835: add locking to pll*_on/off methods
-
-Add missing locking to:
-* bcm2835_pll_divider_on
-* bcm2835_pll_divider_off
-to protect the read modify write cycle for the
-register access protecting both cm_reg and a2w_reg
-registers.
-
-Fixes: 41691b8862e2 ("clk: bcm2835: Add support for programming the
-audio domain clocks")
