[PATCH v3 0/2] staging: octeon: fix probe error path and pow_send_list matching

[Oscar Alejandro Sánchez Lucero via B4 Relay]

Fixed two bugs in drivers/staging/octeon/ethernet.c:

1. Call cvmx_pko_disable() in the cvm_oct_probe() error path to match the
   teardown sequence in cvm_oct_remove().
2. Split pow_send_list on commas using strsep() instead of matching
   substrings with strstr().

  staging: octeon: match exact interface names in pow_send_list

[PATCH v3 1/2] staging: octeon: disable PKO before device removal in probe error path

[Oscar Alejandro Sánchez Lucero via B4 Relay]

From: Oscar Alejandro Sánchez Lucero <aleszlucero@gmail.com>

cvm_oct_remove() calls cvmx_pko_disable() before removing devices and
shutting down PKO. The err_tx error path in cvm_oct_probe() omits this
call.

Add cvmx_pko_disable() to the probe error path to match cvm_oct_remove().

[PATCH v3 2/2] staging: octeon: match exact interface names in pow_send_list

[Oscar Alejandro Sánchez Lucero via B4 Relay]

From: Oscar Alejandro Sánchez Lucero <aleszlucero@gmail.com>

cvm_oct_common_init() searches pow_send_list using strstr(), which matches
substrings instead of exact interface names.

Split a local copy of pow_send_list on comas with strsep() and compare
each entry using strcmp().
