Hello Yakir Yang,
This is a semi-automatic email about new static checker warnings.
The patch 5182c1a556d7: "drm/rockchip: add an common abstracted PSR
driver" from Jul 24, 2016, leads to the following Smatch complaint:
drivers/gpu/drm/rockchip/rockchip_drm_psr.c:228 rockchip_drm_psr_register()
warn: variable dereferenced before check 'encoder' (see line 224)
drivers/gpu/drm/rockchip/rockchip_drm_psr.c
223 {
224 struct rockchip_drm_private *drm_drv = encoder->dev->dev_private;
^^^^^^^^^
Dereference.
225 struct psr_drv *psr;
226 unsigned long flags;
227
228 if (!encoder || !psr_set)
^^^^^^^
Check.
229 return -EINVAL;
230
regards,
dan carpenter
