sensor: lsm6dso: Disable -Wmaybe-uninitialized for lsm6dso_mode_set (cccbc24c) · Commits · Wenxi XU / Hal St

This commit disables the potentially uninitialized variable warning (`-Wmaybe-uninitialized`) for the `lsm6dso_mode_set` function because GCC 12 and above may report a false positive warning claiming that the `ctrl2_ois` variable may be used uninitialized. Note that the `ctrl2_ois` variable is always set when `aux_ctx != NULL` and is accessed if and only if `aux_ctx != NULL`, therefore it may never be used uninitialized as the warning claims.
