hwmon: (ina2xx) Fix current value calculation 2018-11-14T17:11:24+00:00 Nicolin Chen nicoleotsuka@gmail.com 2018-11-14T03:48:54+00:00 38cd989ee38c16388cde89db5b734f9d55b905f9 The current register (04h) has a sign bit at MSB.

hwmon (ina2xx) Fix NULL id pointer in probe() 2018-11-13T17:33:32+00:00 Nicolin Chen nicoleotsuka@gmail.com 2018-11-10T00:42:14+00:00 70df9ebbd82c794ddfbb49d45b337f18d5588dc2 When using DT configurations, the id pointer might turn out to be NULL. Then the driver encounters NULL pointer access: Unable to handle kernel read from unreadable memory at vaddr 00000018 [...] PC is at ina2xx_probe+0x114/0x200 LR is at ina2xx_probe+0x10c/0x200 [...] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b The reason is that i2c core returns the id pointer by matching id_table with client->name, while the client->name is actually using the name from the first string in the DT compatible list, not the best one. So i2c core would fail to match the id_table if the best matched compatible string isn't the first one, and then would return a NULL id pointer. This probably should be fixed in i2c core. But it doesn't hurt to make the driver robust. So this patch fixes it by using the "chip" that's added to unify both DT and non-DT configurations. Additionally, since id pointer could be null, so as id->name: ina2xx 10-0047: power monitor (null) (Rshunt = 1000 uOhm) ina2xx 10-0048: power monitor (null) (Rshunt = 10000 uOhm) So this patch also fixes NULL name pointer, using client->name to play safe and to align with hwmon->name.

When using DT configurations, the id pointer might turn out to
be NULL. Then the driver encounters NULL pointer access:

  Unable to handle kernel read from unreadable memory at vaddr 00000018
  [...]
  PC is at ina2xx_probe+0x114/0x200
  LR is at ina2xx_probe+0x10c/0x200
  [...]
  Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

The reason is that i2c core returns the id pointer by matching
id_table with client->name, while the client->name is actually
using the name from the first string in the DT compatible list,
not the best one. So i2c core would fail to match the id_table
if the best matched compatible string isn't the first one, and
then would return a NULL id pointer.

This probably should be fixed in i2c core. But it doesn't hurt
to make the driver robust. So this patch fixes it by using the

So this patch also fixes NULL name pointer, using client->name
to play safe and to align with hwmon->name.

 "A small update with a couple of new APIs that are useful for some
  small sets of devices:

   - Split up the single_rw flagging to map read and write separately as
     some devices support bulk operations for only read or only write.
