| Subject: phy: mapphone-mdm6600: add gpiolib dependency |
| |
| [ Upstream commit 208d3423ee463ab257908456f6bbca4024ab63f7 ] |
| |
| gcc points out that when CONFIG_GPIOLIB is disabled, |
| gpiod_get_array_value_cansleep() returns 0 but fails to set its output: |
| |
| drivers/phy/motorola/phy-mapphone-mdm6600.c: In function 'phy_mdm6600_status': |
| drivers/phy/motorola/phy-mapphone-mdm6600.c:220:24: error: 'values[0]' is used uninitialized in this function [-Werror=uninitialized] |
| |
| This could be fixed more generally in gpiolib by returning a failure |
| code, but for this specific case, the easier workaround is to add a |
| gpiolib dependency. |
