Subject: [PATCH][next] misc: rtsx: rts5260: make several functions static

From: Colin Ian King <colin.king@...onical.com>

Several functios are local to the source and do not need to be in global
scope, so make them static.

Cleans up sparse warnings:
symbol 'rts5260_get_ocpstat' was not declared. Should it be static?
symbol 'rts5260_get_ocpstat2' was not declared. Should it be static?
symbol 'rts5260_clear_ocpstat' was not declared. Should it be static?
symbol 'rts5260_process_ocp' was not declared. Should it be static?
symbol 'rts5260_init_hw' was not declared. Should it be static?
symbol 'rts5260_set_aspm' was not declared. Should it be static?
