[PATCH] Memory leak in mtd/chips/cfi_cmdset_0020.c

[Felipe W Damasio]

	Hi Andrew,

	Patch against 2.6-test5.

	If other kmallocs failed after successfully allocating a "struct 
mtd_info", it should be freed before returning NULL.

	This function is called by inter_module_register...so I'm not sure it 
should really be freed...please review :)

	Don't have the hardware, so just compilation checked.

	Found by the Stanford Checker.

	Thanks,

Felipe
