Eduardo Valentin 032d405729 thermal: qcom: remove declare local symbols as static
Trivial: remove the following:
drivers/thermal/qcom/tsens-8916.c:103:24: warning: symbol 'ops_8916' was not declared. Should it be static?
drivers/thermal/qcom/tsens-8996.c:76:24: warning: symbol 'ops_8996' was not declared. Should it be static?
drivers/thermal/qcom/tsens-8974.c:235:24: warning: symbol 'ops_8974' was not declared. Should it be static?
drivers/thermal/qcom/tsens-8960.c:279:24: warning: symbol 'ops_8960' was not declared. Should it be static?
