Colin Ian King 78227b671e rtc: tx4939: avoid unintended sign extension on a 24 bit shift ...

[ Upstream commit 347876ad47 ]

The shifting of buf[5] by 24 bits to the left will be promoted to
a 32 bit signed int and then sign-extended to an unsigned long. If
the top bit of buf[5] is set then all then all the upper bits sec
end up as also being set because of the sign-extension. Fix this by
casting buf[5] to an unsigned long before the shift.

Detected by CoverityScan, CID#1465292 ("Unintended sign extension")

Fixes: 0e1492330c ("rtc: add rtc-tx4939 driver")
