The al3010 ambient light sensor driver encoded the highest gain range scale as {0, 1187200}, but IIO_VAL_INT_PLUS_MICRO requires the micro part to be below 1,000,000. The malformed entry caused writes to return -EINVAL, making the top gain range impossible to select from userspace and reporting a bogus value on read. Fixed by re-encoding as {1, 187200}. Marked for backport to stable.

ipu7_init_fw_code_region_by_sys() called pm_runtime_get_sync(), which increments the runtime-PM usage counter even when resume fails. The error path returned without a matching pm_runtime_put(), leaking a reference on every failed resume and eventually preventing the device from ever suspending. Fixed by switching to pm_runtime_resume_and_get(), which drops the reference automatically on failure — consistent with the sibling ipu6 driver.

A second pm_runtime refcount bug in the IPU7 driver: ipu7_resume() called pm_runtime_get_sync() and returned without restoring the counter on error, leaking the reference on every failed resume. Fixed with pm_runtime_resume_and_get() while preserving the intentional return-0-on-error behaviour — resume callbacks should not propagate failures to the PM core. Part of a two-patch series with the companion fix above.
