Subject: [media] pvrusb2-io: no need to check if sp is not NULL
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=19409c8969380ec42e07e5ac2d29d4a33bea572d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[media] pvrusb2-io: no need to check if sp is not NULL

The buffer_complete() routine assumes that sp is not NULL,
otherwise it will fail completely. Btw, this is also
assumed at pvr2_buffer_queue(), with is the routine that
setups the URB handling.

So, remove the bogus for the callback at buffer_complete.

This fix this smatch warning:
	drivers/media/usb/pvrusb2/pvrusb2-io.c:476 buffer_complete() warn: variable dereferenced before check 'sp' (see line 472)
