[media] media, Micronas dvb-t: Fix mem leaks, don't needlessly zero mem, fix spelling
In drivers/media/dvb/frontends/drxd_hard.c::load_firmware() I see 3 small issues: 1) When the 'fw' variable goes out of scope we'll leak the memory allocated to it by request_firmware() by neglecting to call release_firmware(). 2) After a successful request_firmware() we allocate fw->size bytes of memory using kzalloc() only to immediately overwrite all that memory with memcpy(), so asking for zeroed memory seems like wasted effort - just use kmalloc(). 3) In one of the error messages "no memory" lacks a space and is written as "nomemory". This patch fixes all 3 issues. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
