Upstream commit a02dcde595f7 ("Input: touchscreen - avoid bitwise vs logical OR warning") was applied as commit f6e9e7be9b80 ("Input: touchscreen - avoid bitwise vs logical OR warning") in linux-5.4.y but it did not properly account for commit d9265e8a878a ("Input: of_touchscreen - add support for touchscreen-min-x|y"), which means the warning mentioned in the commit message is not fully fixed:

drivers/input/touchscreen/of_touchscreen.c:78:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/input/touchscreen/of_touchscreen.c:78:17: note: cast one or both operands to int to silence this warning drivers/input/touchscreen/of_touchscreen.c:92:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-y", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/input/touchscreen/of_touchscreen.c:92:17: note: cast one or both operands to int to silence this warning 2 warnings generated.

It seems like the 4.19 backport was applied to the 5.4 tree, which did not have any conflicts so no issue was noticed at that point.

Fix up the backport to bring it more in line with the upstream version so that there is no warning.
