MIPS: VPE: Fix a double free and a memory leak in 'release_vpe()'
Pointer on the memory allocated by 'alloc_progmem()' is stored in 'v->load_addr'. So this is this memory that should be freed by 'release_progmem()'. 'release_progmem()' is only a call to 'kfree()'. With the current code, there is both a double free and a memory leak. Fix it by passing the correct pointer to 'release_progmem()'. Fixes: e01402b115ccc ("More AP / SP bits for the 34K, the Malta bits and things. Still wants") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Paul Burton <paulburton@kernel.org> Cc: ralf@linux-mips.org Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: kernel-janitors@vger.kernel.org
