Replace sprintf() with sysfs_emit() and sysfs_emit_at() in sysfs show functions, which are preferred for formatting sysfs output because they provide safer bounds checking. While the current code only emits strings that fit easily within PAGE_SIZE, use sysfs_emit() and sysfs_emit_at() to follow secure coding best practices. This is a mechanical cleanup with a few simple edge cases: - In domains_show(), drop the redundant n < 0 check since neither sprintf() nor sysfs_emit() return negative values. - In powercap_show() and psr_show(), also drop the dead ret < 0 checks. - In ps3_fw_version_show(), normalize the output by adding a terminating newline as suggested by checkpatch. - In vio's modalias_show(), replace the deprecated strcpy() [1] followed by strlen() with sysfs_emit(). Leave validate_show() and the variable-length hv-gpci helpers unchanged since they already have explicit bounds handling, and converting those would be more than a mechanical conversion.
