[PATCH] cpuidle: mvebu: fix duplicate flags assignment
From: Arnd Bergmann
Date: Tue Jan 17 2023 - 11:47:23 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
The added '.flags' value is sometimes ignored here because
it gets overwritten by another initialization:
drivers/cpuidle/cpuidle-mvebu-v7.c:24:33: error: initialized field overwritten [-Werror=override-init]
24 | #define MVEBU_V7_FLAG_DEEP_IDLE 0x10000
| ^~~~~~~
drivers/cpuidle/cpuidle-mvebu-v7.c:69:43: note: in expansion of macro 'MVEBU_V7_FLAG_DEEP_IDLE'
69 | .flags = MVEBU_V7_FLAG_DEEP_IDLE,
| ^~~~~~~~~~~~~~~~~~~~~~~
drivers/cpuidle/cpuidle-mvebu-v7.c:24:33: note: (near initialization for 'armadaxp_idle_driver.states[2].flags')

Merge the two fields into one.
