This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions.The label err_register is removed as it is no longer required. The following Coccinelle semantic patch was used for making the change: @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by:Himangi Saraogi <himangi774@gmail.com> Signed-off-by:

vb2_get_vma() copy the content of the vma to a new structure but set some of its pointers to NULL. One of this pointer is used by follow_pte() called by follow_pfn() on io memory. This can lead to a NULL pointer derreference. The version of vma that has not been cleared must be used.

Function del_timer() does not guarantee that timer was really deleted. If the timer handler is beeing executed at the moment, the function does nothing. So, we have a race between del_timer() and kfree(), and it's possible to use already freed memory in the handler. Signed-off-by:

The else statement here is not aligned with the correct if statement. I think the code works as intended and it's just the indenting which is wrong. Also kernel style says we should use curly braces here so I have added those. Signed-off-by:

em28xx_compression_disable() is a single line function which is called only one time and this call also isn't needed. Register 0x26 is always configured as part of the scaler configuration, which in turn is always done when the resolution changes. And the initial resolution setting is applied at first device open.
