net: enetc: improve the interface for obtaining phc_index

[PATCH v2 net-next 0/2] net: enetc: improve the interface for obtaining phc_index

Posted by Wei Fang 1 week, 5 days ago

The first patch is to fix the issue that a sleeping function is called
in the context of rcu_read_lock(). The second patch is to use the generic
API instead of the custom API to get phc_index. In addition, the second
patch depends on the first patch to work.

Note, the first patch is a fix, but the issue does not exist in the net
tree, so the target tree is net-next.

v2 changes:
1. Add patch 1 to fix the issue that sleeping function called from
   invalid context
2. Fix the build warning of patch 2.
