It's usually a common pattern to free() the memory that we allocated. Implement this here to stop leaking memory. Also, add a debug output when BAR configuration fails to follow suit.

NOTE: I think we can do without the memory allocation here altogether.
Is there any upper limit on the number of dummy bytes that can go with a SF command? If so, we can just allocate that buffer on a stack and be done with it.diff --git a/drivers/mtd/spi/sf_ops.c b/drivers/mtd/spi/sf_ops.c index ef91b92..29a7867 100644 --- a/drivers/mtd/spi/sf_ops.c +++ b/drivers/mtd/spi/sf_ops.c @@ -398,8 +398,10 @@ int spi_flash_cmd_read_ops(struct spi_flash *flash, u32 offset,

Feel free to drop this when applying.
Btw. the information printing is quite inconsistent in this stuff.
