[PATCH 5.4 02/34] Input: touchscreen - Fix backport of a02dcde595f7cbd240ccd64de96034ad91cffc40

[Greg Kroah-Hartman]

From: Nathan Chancellor <nathan@xxxxxxxxxx>

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.
