Having module device table based on PNP id produces the following warning:
CC drivers/input/touchscreen/htcpen.o
drivers/input/touchscreen/htcpen.c:50: warning: 'pnp_ids' defined but not used
This happens because it is not a PNP driver, bit rather ISA driver and
pnp_ids table is not used anywhere. To fix this issue let's switch to
DMI-based module table instead,

This variant was introduced in
i2c: boilerplate function for byte swapped smbus_write/read_word_data
This also has the side effect of ensuring any errors from the i2c
read and no longer mangled.

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.
The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
struct spi_driver _driver = {
.driver = {
- .bus = &spi_bus_type,
},
};
// </smpl>

With commit 67d0a07544 we mark strict_strtox

Also change long to appropriate types, and return error conditions
from kstrtox separately, as Dmitry sugguests.

Sysfs attribute show methods are always passed a buffer of length
PAGE_SIZE. To keep from overwriting this buffer and causing havoc, use
snprintf() to guarantee we never write more than the buffer can hold.
In addition, at least for my touchscreen, the number and size of objects
was far too big to fit in a single 4K page. Therefore, this patch also
trims some redundant framing text to leave more room for actual data.
