Subject: [PATCH] block: remove a dead check in show_partition
Git-commit: e3b3bad3f29878d13fdbc96f9e59674bd9b06bae
Patch-mainline: v5.17-rc1
References: jsc#PED-1183
disk_max_parts never returns 0 given that ->minors for devices not using
the extended dev_t must be non-zero, and disk_max_parts always returns
DISK_MAX_PARTS for the latter.
