The LM73 supports four A/D conversion resolutions. The default used by the existing lm73 driver is the chip's default, 11-bit (0.25 C/LSB). This patch enables changing of this resolution from userspace via the update_interval sysfs attribute. Full details on usage are included in Documentation/hwmon/lm73.

While the LM73 is only specified for temperatures from -40 to +150 degrees C, its power-up minimum and maximum temperature limits are -256 and +255.75 degrees C. For better consistency and to avoid confusion, clamp limits to the power-up limits and not to -40 / +150 degrees C. Signed-off-by: NGuenter Roeck <linux@roeck-us.net>

Without this patch, the SHT15 driver may fail silently with a non-bidirectional data line and/or an input-only clock line. This patch checks the return value of gpio_direction_* function calls and returns the error code (if any) to the caller. If an error occurs in the read work function (work_funct_t), we wake the queue up directly without updating the data->state flag, to notice the waiter of the I/O error. The patch also makes minor cleanups: s/error_ret/unlock for some labels and uses devm_gpio_request_one() for the clock line.

This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers.

If an LM73 device does not exist on an I2C bus, attempts to communicate with the device result in an error code returned from the i2c read/write functions. The current lm73 driver casts that return value from a s32 type to a s16 type, then converts it to a temperature in celsius. Because negative temperatures are valid, it is difficult to distinguish between an error code printed to the response buffer and a negative temperature recorded by the sensor. The solution is to evaluate the return value from the i2c functions before performing any temperature calculations. If the i2c function did not succeed, the error code should be passed back through the virtual file system layer instead of being printed into the response buffer.

However this shows that the code isn't very robust and future changes could easily introduce a buffer overflow. So let's add a safety check to prevent that and make smatch happy.

So far, we use the NM10 Express Chipset PCI chip ID to detect TjMax for Atom CPUs with model 0x1c. As it turns out, we can use the CPU stepping (x86_mask) for the same purpose; stepping is 10 for all model 0x1c CPUs with TjMax of 100 degrees C. This was verified by checking the output of /proc/cpuinfo for the respective CPUs (D4xx, D5xx, N4xx, N5xx). Other CPUs currently covered by the same code (Exx, Z6xx, Z2460) are not supported by the NM10 Express Chipset. Most of those CPUs have TjMax of 90 degrees C, except for E6xxT models which have a TjMax of 110 degrees C. E6xxT CPUs can however not be detected by software. Calculate TjMax for Atom CPUs as follows. Note that the listed values are not correct in some cases (230, 330). tjmax_table is used for those to override the default values. ID Stepping TjMax Models 0x1c 10 100 D4xx, N4xx, D5xx, N5xx 0x1c not 10 90 Z5xx, N2xx, 230, 330, others 0x26 - 90 Atom Tunnel Creek (Exx), Lincroft (Z6xx) 0x27 - 90 Atom Medfield (Z2460) 0x36 - 100 Atom Cedar Trail (N2xxx, D2xxx) Also drop the module dependency on PCI.
