Subject: [PATCH 5.10 250/593] hwmon: (lm70) Use device_get_match_data()

From: Stephen Boyd <swboyd@...omium.org>

[ Upstream commit 6e09d75513d2670b7ab91ab3584fc5bcf2675a75 ]

Use the more modern API to get the match data out of the of match table.
This saves some code, lines, and nicely avoids referencing the match
table when it is undefined with configurations where CONFIG_OF=n.
