This series fixes bugs in drivers/hwmon/

1. pt5161l: Undersized stack buffer for SMBus block read, and
   unexpected positive return when retries are exhausted
2. isl28022: Integer overflow in power calculation on 32-bit
3. powerz: Use-after-free race on USB disconnect, and signal
   handling bug in completion wait

Changes since v1:
- Patch 1/3 (pt5161l): Also fix the case where
  i2c_smbus_read_block_data() returns a positive byte count on
  length mismatch after all retries are exhausted. Callers treated
  this as success. Return -EIO instead.
- Patch 2/3 (isl28022): Switch from s64/div_s64() to u64/div_u64()
  since power is inherently non-negative. This avoids implicit
  narrowing of the u32 shunt divisor to s32.
- Patch 3/3 (powerz): Also fix signal handling in
  wait_for_completion_interruptible_timeout(). The original code
  only handles timeout (ret==0) but not signals (ret==-ERESTARTSYS),
  which skips usb_kill_urb() and falls through to access stale URB
  data. Return -ENODEV instead of -EIO on disconnected device for
  clearer semantics.
