Subject: OMAP2+: PM: Initialise sleep_switch to a non-valid value
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6349b96b439515e1100cd98f27ff55a262f558a3;p=linux-beck.git

OMAP2+: PM: Initialise sleep_switch to a non-valid value

sleep_switch which is initialised to 0 in omap_set_pwrdm_state
happens to be a valid sleep_switch type (FORCEWAKEUP_SWITCH)
which are defined as:

 #define FORCEWAKEUP_SWITCH      0
 #define LOWPOWERSTATE_SWITCH    1

This causes the function to wrongly program some clock domains
even when the Powerdomain is in ON state.
