+Subject: media: dw2102: fix a potential buffer overflow
+
+From: Mauro Carvalho Chehab <mchehab@kernel.org>
+
+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")
