[PATCH 5.15 06/28] net: enetc: use EXPORT_SYMBOL_GPL for enetc_phc_index

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christoph Hellwig <hch@xxxxxx>

commit 569820befb16ffc755ab7af71f4f08cc5f68f0fe upstream.

enetc_phc_index is only used via symbol_get, which was only ever
intended for very internal symbols like this one.  Use EXPORT_SYMBOL_GPL
for it so that symbol_get can enforce only being used on
EXPORT_SYMBOL_GPL symbols.
