[ Upstream commit 17ab1ea679be48d905559d968a7622f5f212de6e ]
When CONFIG_PM is disabled, the driver fails to build:
drivers/accel/ivpu/ivpu_pm.c: In function 'ivpu_rpm_get': drivers/accel/ivpu/ivpu_pm.c:240:84: error: 'struct dev_pm_info' has no member named 'usage_count' 240 | ivpu_dbg(vdev, RPM, "rpm_get count %d\n", atomic_read(&vdev->drm.dev->power.usage_count)); | ^ include/linux/dynamic_debug.h:223:29: note: in definition of macro '__dynamic_func_call_cls' 223 | func(&id, ##__VA_ARGS__); \ | ^~~~~~~~~~~ include/linux/dynamic_debug.h:249:9: note: in expansion of macro '_dynamic_func_call_cls' 249 | _dynamic_func_call_cls(_DPRINTK_CLASS_DFLT, fmt, func, ##__VA_ARGS__) | ^~~~~~~~~~~~~~~~~~~~~~ include/linux/dynamic_debug.h:272:9: note: in expansion of macro '_dynamic_func_call' 272 | _dynamic_func_call(fmt, __dynamic_dev_dbg, \ | ^~~~~~~~~~~~~~~~~~ include/linux/dev_printk.h:155:9: note: in expansion of macro 'dynamic_dev_dbg' 155 | dynamic_dev_dbg(dev, dev_fmt(fmt), ##__VA_ARGS__) | ^~~~~~~~~~~~~~~ drivers/accel/ivpu/ivpu_drv.h:65:17: note: in expansion of macro 'dev_dbg' 65 | dev_dbg((vdev)->drm.dev, "[%s] " fmt, #type, ##args); \ | ^~~~~~~ drivers/accel/ivpu/ivpu_pm.c:240:9: note: in expansion of macro 'ivpu_dbg' 240 | ivpu_dbg(vdev, RPM, "rpm_get count %d\n", atomic_read(&vdev->drm.dev->power.usage_count)); | ^~~~~~~~
It would be possible to rework these statements to only conditionally print the reference counter, or to make the driver depend on CONFIG_PM, but my impression is that these are not actually needed at all if the driver generally works, or they could be put back when required. Just remove all four of these to make the driver build in all configurations.
