This patch fixes these checkpatch.pl errors around a single switch-case block:

ERROR: switch and case should be at the same indent
ERROR: trailing statements should be on next line

More specifically, the fix has been applied to the five occurances of the errors listed below.

ERROR: switch and case should be at the same indent #1100: FILE: adm8211.c:1100:
+ switch (cline) {
[...]
+ default: reg |= (0x0 << 14);

ERROR: trailing statements should be on next line
#1101: FILE: adm8211.c:1101:
+ case 0x8: reg |= (0x1 << 14);

ERROR: trailing statements should be on next line
#1103: FILE: adm8211.c:1103:
+ case 0x16: reg |= (0x2 << 14);

ERROR: trailing statements should be on next line
#1105: FILE: adm8211.c:1105:
+ case 0x32: reg |= (0x3 << 14);

ERROR: trailing statements should be on next line
#1107: FILE: adm8211.c:1107:
+ default: reg |= (0x0 << 14);

The PCI cache line size value was being compared against decimal values prefixed with 0x.

Fixed the literals to use the correct hex values.

This has not been tested due to lack of hardware. However, the value in cline is PCI cache line size, which is the CPU's cache line size. It is less likely for cache line sizes to be 22 or 50, and more likely for them to be 16 or 32. Also, as far as I understand, cache line size is used for things like aligning DMA requests with CPU cache line, which improve performance but wouldn't break anything if the value doesn't match. In this case, we will fall through to the default case which leaves reg unchanged.
