thermal/drivers/tsens: Fix null pointer dereference

Browse source

[ Upstream commit d998ddc86a ]

compute_intercept_slope() is called from calibrate_8960() (in tsens-8960.c)
as compute_intercept_slope(priv, p1, NULL, ONE_PT_CALIB) which lead to null
pointer dereference (if DEBUG or DYNAMIC_DEBUG set).
Fix this bug by adding null pointer check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
