4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mauro Carvalho Chehab <mchehab@xxxxxxxxxx>
commit 1c73d0b29d04bf4082e7beb6a508895e118ee30d upstream.
As pointed by smatch:
drivers/media/usb/dvb-usb/dw2102.c:802 su3000_i2c_transfer() error: __builtin_memcpy() '&state->data[4]' too small (64 vs 67)
That seemss to be due to a wrong copy-and-paste.
Fixes: 0e148a522b84 ("media: dw2102: Don't translate i2c read into write")
