PM / sleep: Fix test_suspend after sleep state rework
When passing "test_suspend=mem" to the kernel: PM: can't test 'mem' suspend state and the suspend test is not run. Commit 406e79385f3223d8 ("PM / sleep: System sleep state selection interface rework") changed pm_labels[] from a contiguous NULL-terminated array to a sparse array (with the first element unpopulated), breaking the assumptions of the iterator in setup_test_suspend(). Iterate from PM_SUSPEND_MIN to PM_SUSPEND_MAX - 1 to fix this. Fixes: 406e79385f3223d8 (PM / sleep: System sleep state selection interface rework) Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rafael J.
