+Subject: pwm: img: fix pwm clock lookup
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+22e8e19 has introduced a regression in the imgchip->pwm_clk lookup, whereas
+the clock name has also been renamed to "imgchip". This causes the driver
+failing to load:
+
+[    0.546905] img-pwm 18101300.pwm: failed to get imgchip clock
+[    0.553418] img-pwm: probe of 18101300.pwm failed with error -2
+
+Fix this lookup by reverting the clock name back to "pwm".
