* hwmon: (lm92) Fix whitespace issuesGuenter Roeck2018-10-111-6/+8
| | | | | | | | | | | Smatch complains: drivers/hwmon/lm92.c:209 set_temp_hyst() warn: inconsistent indenting While at it, fix various other whitespace issues reported by checkpatch (double empty lines, missing empty lines, whitespace at empty line).

* hwmon: (lm92) Add max6635 to lm92_id[]Alvaro G. M2018-03-221-2/+3
| | | | | | | | | Since autodetection of this chip was removed, it makes sense to add prefix max6635 so that the device can be instantiated by its actual name.

* hwmon: (lm92) Do not try to detect MAX6635Alvaro G. M2018-03-221-58/+0
| | | | | | | | | | | | Maxim MAX663x family are mostly compatible with LM92, but they lack any identification register. Weakening the detect function would make it prone to false positives, and current one doesn't detect all chips. Therefore, the detect function for max6635 devices is removed in favor of explicit device instatiation.

* hwmon: (lm92) use permission-specific DEVICE_ATTR variantsJulia Lawall2017-01-021-5/+5
| | | | | | | | | | | | | Use DEVICE_ATTR_RO for read-only attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size.

* hwmon: (lm92) Prevent overflow problem when writing large limitsAxel Lin2014-08-061-7/+6
| | | | | | | | | | | | | | | | | | | | On platforms with sizeof(int) < sizeof(long), writing a temperature limit larger than MAXINT will result in unpredictable limit values written to the chip. Avoid auto-conversion from long to int to fix the problem. The hysteresis temperature range depends on the value of data->temp[attr->index], since val is subtracted from it. Use a wider clamp, [-120000, 220000] should do to cover the possible range. Also add missing TEMP_TO_REG() on writes into cached hysteresis value. Also uses clamp_val to simplify the code a bit.

* [PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare2006-01-061-1/+0

If any driver really doesn't want to be notified when i2c adapters are added, that driver can simply omit to set .attach_adapter.
