Subject: [PATCH 12/21] scsi: qedi: fix building with LTO
Git-commit: 779936faf4f1210a2a6c3a2ccc63cd74a61769ed
Patch-mainline: v4.17-rc1
References: bsc#1086315
When link-time optimizations are enabled, qedi fails to build because
of mismatched prototypes:
drivers/scsi/qedi/qedi_gbl.h:27:37: error: type of 'qedi_dbg_fops' does not match original declaration [-Werror=lto-type-mismatch]
extern const struct file_operations qedi_dbg_fops;
^
drivers/scsi/qedi/qedi_debugfs.c:239:30: note: 'qedi_dbg_fops' was previously declared here
const struct file_operations qedi_dbg_fops[] = {
^
drivers/scsi/qedi/qedi_gbl.h:26:32: error: type of 'qedi_debugfs_ops' does not match original declaration [-Werror=lto-type-mismatch]
extern struct qedi_debugfs_ops qedi_debugfs_ops;
^
drivers/scsi/qedi/qedi_debugfs.c:102:25: note: 'qedi_debugfs_ops' was previously declared here
struct qedi_debugfs_ops qedi_debugfs_ops[] = {
This changes the declaration to match the definition, and adapts the
users as necessary. Since both array can be constant here, I'm adding
the 'const' everywhere for consistency.
