Xia Fukun 7c852e8f93 drm/i915/bios: fix a memory leak in generate_lfp_data_ptrs 
[ Upstream commit 1382901f75 ]

When (size != 0 || ptrs->lvds_ entries != 3), the program tries to
free() the ptrs. However, the ptrs is not created by calling kzmalloc(),
but is obtained by pointer offset operation.
This may lead to memory leaks or undefined behavior.

Fix this by replacing the arguments of kfree() with ptrs_block.
