ssb: get alp clock from devices with PMU

Hello Hauke Mehrtens,

The patch f924e1e989b0: "ssb: get alp clock from devices with PMU" from Dec 5, 2012, leads to the following static checker warning:

drivers/ssb/driver_chipcommon_pmu.c:624 ssb_pmu_get_alp_clock_clk0()
warn: shift is higher precedence than mask

drivers/ssb/driver_chipcommon_pmu.c
619 static u32 ssb_pmu_get_alp_clock_clk0(struct ssb_chipcommon *cc) 620 {
621 u32 crystalfreq;
622 const struct pmu0_plltab_entry *e = NULL;
623
624 crystalfreq = chipco_read32(cc, SSB_CHIPCO_PMU_CTL) &
625 SSB_CHIPCO_PMU_CTL_XTALFREQ >> SSB_CHIPCO_PMU_CTL_XTALFREQ_SHIFT;

This was probably supposed to be:

		crystalfreq = (chipco_read32(cc, SSB_CHIPCO_PMU_CTL) &
			       SSB_CHIPCO_PMU_CTL_XTALFREQ) >> SSB_CHIPCO_PMU_CTL_XTALFREQ_SHIFT;

   626          e = pmu0_plltab_find_entry(crystalfreq);
   627          BUG_ON(!e);
   628          return e->freq * 1000;

629 }
