From: Ruoyu Wang Date: Tue, 9 Jun 2026 05:26:47 +0000 (+0800) Subject: spi: meson-spifc: fix runtime PM leak on remove X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=606c0826bd90384a54571c0c5475ca41f50164ea;p=thirdparty%2Flinux.git spi: meson-spifc: fix runtime PM leak on remove pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error. meson_spifc_remove() uses it to resume the controller before disabling runtime PM, but never drops the usage counter again. Balance the get with pm_runtime_put_noidle() after disabling runtime PM, matching the teardown pattern used by other SPI controller drivers. Found by static analysis. I do not have hardware to test this.
