Subject[PATCH] drivers/thermal/spear_thermal.c: use devm_clk_get
Date
From: Julia Lawall <Julia.Lawall@lip6.fr>

devm_clk_get allocates a resource that is released when a driver detaches.
This patch uses devm_clk_get for data that is allocated in the probe
function of a platform device and is only released in the remove function.

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>

---
I was not able to compile this code. At one point, devm_clk_get was not
supported for all architectures. If that is still the case, and the code
doesn't compile, then just ignore the patch.
