Commit 6579a03e68ff ("drm/bridge: analogix_dp: Remove the unnecessary
calls to clk_disable_unprepare() during probing") removed the mismatched
clock_disable calls from analogix_dp_probe.
But that patch was created and sent before
commit e5e9fa9f7aad ("drm/bridge: analogix_dp: Add support to get panel
from the DP AUX bus") was merged, so couldn't know about this change.
So in the original patch the last change is
if (ret) {
dev_err(&pdev->dev, "failed to request irq\n");
- goto err_disable_clk;
+ return ERR_PTR(ret);
}
disable_irq(dp->irq);
return dp;
-
-err_disable_clk:
- clk_disable_unprepare(dp->clock);
- return ERR_PTR(ret);
}
EXPORT_SYMBOL_GPL(analogix_dp_probe);
the analogix_dp_core.c actually now has the runtime-pm handling between
disable_irq() and return do introducing another goto err_clk_disable there.
So remove that one too and return an error pointer, to not create build
breakage.
Fixes: 6579a03e68ff ("drm/bridge: analogix_dp: Remove the unnecessary calls to clk_disable_unprepare() during probing")

When I reviewed the original patch, I failed to see that difference :-(
But I do wonder how dim was able to apply the original patch.
