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 Workqueue: pm pm_runtime_work\n Call trace:\n  ...\n  clk_core_disable from clk_disable+0x28/0x34\n  clk_disable from i2s_runtime_suspend+0x58/0x68 [snd_soc_i2s]\n  i2s_runtime_suspend [snd_soc_i2s] from genpd_runtime_suspend+0xc4/0x298\n  genpd_runtime_suspend from __rpm_callback+0x48/0x18c\n  __rpm_callback from rpm_callback+0x4c/0x50\n  rpm_callback from rpm_suspend+0xf4/0x718\n  rpm_suspend from pm_runtime_work+0x9c/0xa0\n  ...\n\nFix this by enabling op_clk in probe right after getting it, so the clock\nstate matches the runtime PM active state, and by disabling it in remove.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/2c64c30d493d82d5edc95811cede0083e1195822","tags":[]},{"url":"https://git.kernel.org/stable/c/5dac6bf09b5a4fff2433629801309c3884c3e94a","tags":[]},{"url":"https://git.kernel.org/stable/c/64bb35079dcbc67901da1fe8c52c234cbcd17df3","tags":[]},{"url":"https://git.kernel.org/stable/c/7529254014764ae0b8c33d5c61a58f36c65b1a1c","tags":[]},{"url":"https://git.kernel.org/stable/c/a728c12f8bd89947894e227d0f4f83a895ac9ab7","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
