Subject: platform/chrome: cros_ec_lpc - Use existing function to check EC result
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fbf40727c781a3b8562e76a86cd08a111414d1c7;p=linux-beck.git

platform/chrome: cros_ec_lpc - Use existing function to check EC result

Commit 6db07b633658 ("mfd: cros_ec: Check result code from EC messages")
added a common cros_ec_check_result() function that can be used to check
the ec_msg->result for errors and warns about them.

Use the existing function instead of duplicating same check in the driver.
