From: Nuno Sa Date: Fri, 20 Sep 2024 07:22:52 +0000 (+0200) Subject: Input: adp5588-keys - fix check on return code X-Git-Url: https://repo.jachan.dev/J-linux.git/commitdiff_plain/eb017f4ea13b1a5ad7f4332279f2e4c67b44bdea Input: adp5588-keys - fix check on return code During adp5588_setup(), we read all the events to clear the event FIFO. However, adp5588_read() just calls i2c_smbus_read_byte_data() which returns the byte read in case everything goes well. Hence, we need to explicitly check for a negative error code instead of checking for something different than 0.
