Subject: [PATCH] [linux-next] pwm: lpss: fix const qualifier discard warning

Fixing this warning:
drivers/pwm/pwm-lpss.c: In function ‘pwm_lpss_probe_pci’:
drivers/pwm/pwm-lpss.c:192:2: warning: passing argument 3 of ‘pwm_lpss_probe’ discards ‘const’ qualifier from pointer target type [enabled by default]
  lpwm = pwm_lpss_probe(&pdev->dev, &pdev->resource[0], info);
  ^
drivers/pwm/pwm-lpss.c:130:30: note: expected ‘struct pwm_lpss_boardinfo *’ but argument is of type ‘const struct pwm_lpss_boardinfo *’
 static struct pwm_lpss_chip *pwm_lpss_probe(struct device *dev,

That warning was introduced in commit 093e00bb3f82f3c67e2d1682e316fc012bcd0d92
("pwm: lpss: Add support for PCI devices").
