Subject: [PATCH 1/1] of: unittest: update text of expected warnings

From: Frank Rowand <frank.rowand@...y.com>

The text of various warning messages triggered by unittest has
changed.  Update the text of expected warnings to match.

The expected vs actual warnings are most easily seen by filtering
the boot console messages with the of_unittest_expect program at
https://github.com/frowand/dt_tools.git.  The filter prefixes
problem lines with '***', and prefixes lines that match expected
errors with 'ok '.  All other lines are prefixed with '   '.
Unrelated lines have been deleted in the following examples.

The mismatch appears as:

-> ### dt-test ### start of unittest - you will see error messages
      OF: /testcase-data/phandle-tests/consumer-a: #phandle-cells = 3 found 1
   ** of_unittest_expect WARNING - not found ---> OF: /testcase-data/phandle-tests/consumer-a: #phandle-cells = 3 found -1
      OF: /testcase-data/phandle-tests/consumer-a: #phandle-cells = 3 found 1
   ** of_unittest_expect WARNING - not found ---> OF: /testcase-data/phandle-tests/consumer-a: #phandle-cells = 3 found -1
      OF: /testcase-data/phandle-tests/consumer-b: #phandle-cells = 2 found 1
   ** of_unittest_expect WARNING - not found ---> OF: /testcase-data/phandle-tests/consumer-b: #phandle-cells = 2 found -1
      platform testcase-data:testcase-device2: error -ENXIO: IRQ index 0 not found
   ** of_unittest_expect WARNING - not found ---> platform testcase-data:testcase-device2: IRQ index 0 not found
   -> ### dt-test ### end of unittest - 254 passed, 0 failed
   ** EXPECT statistics:
   **
   **   EXPECT found          :   42
   **   EXPECT not found      :    4

With this commit applied, the mismatch is resolved:

   -> ### dt-test ### start of unittest - you will see error messages
   ok OF: /testcase-data/phandle-tests/consumer-a: #phandle-cells = 3 found 1
   ok OF: /testcase-data/phandle-tests/consumer-a: #phandle-cells = 3 found 1
   ok OF: /testcase-data/phandle-tests/consumer-b: #phandle-cells = 2 found 1
   ok platform testcase-data:testcase-device2: error -ENXIO: IRQ index 0 not found
   -> ### dt-test ### end of unittest - 254 passed, 0 failed
   ** EXPECT statistics:
   **
   **   EXPECT found          :   46
   **   EXPECT not found      :    0

Fixes: 2043727c2882 ("driver core: platform: Make use of the helper function dev_err_probe()")
Fixes: 94a4950a4acf ("of: base: Fix phandle argument length mismatch error message")
