Because some underlying bus APIs (like USB) don't like data buffers in the stack or vmalloced areas, the i2400m driver provides a scratch buffer (i2400m->bm_cmd_buf) for said low-level drivers to copy command data to before passing it to said API. This is only used during boot mode. However, at some the code was copying the buffer even when the command was already specified in said buffer. This is ok, but it needs to be more careful. As thus, change so that: (a) the copy happens only if command buffer is not the scratch buffer (b) use memmove() in case there is overlapping Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com> |
