Title
drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func This commit adds a null check for the set_output_gamma function pointer in the dcn20_set_output_transfer_func function. Previously, set_output_gamma was being checked for null at line 1030, but then it was being dereferenced without any null check at line 1048. This could potentially lead to a null pointer dereference error if set_output_gamma is null. To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a null check for set_output_gamma before the call to set_output_gamma at line 1048.

Esto podr\u00eda conducir potencialmente a un error de desreferencia de puntero nulo si set_output_gamma es nulo. Para solucionar esto, ahora nos aseguramos de que set_output_gamma no sea nulo antes de desreferenciarlo. Hacemos esto agregando una comprobaci\u00f3n NULL para set_output_gamma antes de la llamada a set_output_gamma en la l\u00ednea 1048."

Previously,\nset_output_gamma was being checked for null at line 1030, but then it\nwas being dereferenced without any null check at line 1048. This could\npotentially lead to a null pointer dereference error if set_output_gamma\nis null.\n\nTo fix this, we now ensure that set_output_gamma is not null before\ndereferencing it.

Previously,\nset_output_gamma was being checked for null at line 1030, but then it\nwas being dereferenced without any null check at line 1048. This could\npotentially lead to a null pointer dereference error if set_output_gamma\nis null.\n\nTo fix this, we now ensure that set_output_gamma is not null before\ndereferencing it. We do this by adding a null check for set_output_gamma\nbefore the call to set_output_gamma at line 1048."
