The runtime PM suspend\ncallback disables both clocks, so the first runtime suspend after probe\ndisables op_clk once more than it was enabled.\n\nOn Exynos5250 Arndale both clocks resolve to the same EXYNOS_I2S_BUS gate,\nso this triggers the following warning during boot:\n\n WARNING: drivers/clk/clk.c:1270 at clk_core_disable+0xe4/0x23c, CPU#0: kworker/u8:3/45\n i2s_bus already disabled\n ...\n

remove.","state":0,"publishedAt":"2026-10-26T14:51:59.055+00:00","modifiedAt":"2026-10-26T14:51:59.055+00:00","affected":[{"ecosystem":"Vendor
